FIELD OF INVENTION

The present disclosure relates to the biosynthesis of cannabinoids and cannabinoid precursors in recombinant cells.

BACKGROUND

Cannabinoids are chemical compounds that may act as ligands for endocannabinoid receptors and have multiple medical applications. Traditionally, cannabinoids have been isolated from plants of the genus Cannabis. The use of plants for producing cannabinoids is inefficient, however, with isolated products restricted to the primary endogenous Cannabis compounds, and the cultivation of Cannabis plants is restricted in many jurisdictions. Cannabinoids can also be produced through chemical synthesis (see, e.g., U.S. Pat. No. 7,323,576 to Souza et al). However, such methods suffer from low yields and high cost. Production of cannabinoids, cannabinoid analogs, and cannabinoid precursors using engineered organisms may provide an advantageous approach to meet the increasing demand for these compounds.

BRIEF DESCRIPTION OF DRAWINGS

The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component that is illustrated in various figures is represented by a like numeral. For purposes of clarity, not every component may be labeled in every drawing. In the drawings:

FIG. 1 is a schematic depicting the native Cannabis biosynthetic pathway for production of cannabinoid compounds, including five enzymatic steps mediated by: (R1a) acyl activating enzymes (AAE); (R2a) olivetol synthase enzymes (OLS); (R3a) olivetolic acid cyclase enzymes (OAC); (R4a) cannabigerolic acid synthase enzymes (CBGAS); and (R5a) terminal synthase enzymes (TS). Formulae 1a-11a correspond to hexanoic acid (1a), hexanoyl-CoA (2a), malonyl-CoA (3a), 3,5,7-trioxododecanoyl-CoA (4a), olivetol (5a), olivetolic acid (6a), geranyl pyrophosphate (7a), cannabigerolic acid (8a), cannabidiolic acid (9a), tetrahydrocannabinolic acid (10a), and cannabichromenic acid (11a). Hexanoic acid is an exemplary carboxylic acid substrate; other carboxylic acids may also be used (e.g., butyric acid, isovaleric acid, octanoic acid, decanoic acid, etc.; see e.g., FIG. 3 below). The enzymes that catalyze the synthesis of 3,5,7-trioxododecanoyl-CoA and olivetolic acid are shown in R2a and R3a, respectively, and can include multi-functional enzymes that catalyze the synthesis of 3,5,7-trioxododecanoyl-CoA and olivetolic acid. The enzymes cannabidiolic acid synthase (CBDAS), tetrahydrocannabinolic acid synthase (THCAS), and cannabichromenic acid synthase (CBCAS) that catalyze the synthesis of cannabidiolic acid, tetrahydrocannabinolic acid, and cannabichromenic acid, respectively, are shown in step R5a. FIG. 1 is adapted from Carvalho et al. “Designing Microorganisms for Heterologous Biosynthesis of Cannabinoids” (2017) FEMS Yeast Research June 1; 17(4), which is incorporated by reference in its entirety.

FIG. 2 is a schematic depicting a heterologous biosynthetic pathway for production of cannabinoid compounds, including five enzymatic steps mediated by: (R1) acyl activating enzymes (AAE); (R2) polyketide synthase enzymes (PKS) or bifunctional polyketide synthase-polyketide cyclase enzymes (PKS-PKC); (R3) polyketide cyclase enzymes (PKC) or bifunctional PKS-PKC enzymes; (R4) prenyltransferase enzymes (PT); and (R5) terminal synthase enzymes (TS). Any carboxylic acid of varying chain lengths, structures (e.g., aliphatic, alicyclic, or aromatic) and functionalization (e.g., hydroxylic-, keto-, amino-, thiol-, aryl-, or alogeno-) may also be used as precursor substrates (e.g., thiopropionic acid, hydroxy phenyl acetic acid, norleucine, bromodecanoic acid, butyric acid, isovaleric acid, octanoic acid, decanoic acid, etc).

FIG. 3 is a non-exclusive representation of select putative precursors for the cannabinoid pathway in FIG. 2.

FIG. 4 is a graph showing activity of E. coli strains expressing candidate AAEs as measured by a 5,5′-dithiobis-(2-nitrobenzoic acid) (“DTNB”) assay. Lysates of E. coli expressing candidate AAEs were assayed for ligation activity of free CoA to either butyrate or hexanoate. Activity was quantified by measuring the decrease in absorbance at 412 nm, corresponding to a decrease of free CoA in solution. Error bars represent the standard deviation of 2 independent measurements. Negative control strain t49568 expresses an aldehyde dehydrogenase protein from Y. lipolytica (corresponding to Uniprot ID Q6C5T1).

FIGS. 5A-5B show a plasmid used to express AAE and OLS proteins in S. cerevisiae. The coding sequence for the enzyme being expressed (labeled “Library gene”) is driven by the GAL1 promoter. The plasmid contains markers for both yeast (URA3) and bacteria (ampR), as well as origins of replication for yeast (2 micron), bacteria (pBR322), and phage (f1).

FIG. 6 is a graph showing activity of S. cerevisiae strains expressing candidate AAEs as measured by a DTNB assay. Lysates of S. cerevisiae expressing candidate AAEs were assayed for ligation activity of free CoA to hexanoate. Activity was quantified by measuring the decrease in absorbance at 412 nm, corresponding to a decrease of free CoA in solution. Error bars represent the standard deviation of 3 independent measurements. Negative control strain t390338 expresses GFP.

FIGS. 7A-7C show a sequence alignment of acyl activating enzymes (AAEs). An alignment of t51477 (SEQ ID NO: 65), t49578 (SEQ ID NO: 63), t49594 (SEQ ID NO: 64), t392878 (SEQ ID NO: 68), t392879 (SEQ ID NO: 69), t55127 (SEQ ID NO: 66), and t55128 (SEQ ID NO: 67) is shown. The sequence alignment was conducted using Clustal Omega. See, e.g., Chojnacki et al., Nucleic Acids Res. 2017 Jul. 3; 45(W1):W550-W553.

FIG. 8 is a graph showing olivetol production by S. cerevisiae strains expressing OLS candidate enzymes. Peak areas obtained via LC/MS quantification were normalized to an internal standard for olivetol. Normalized peak areas were further normalized to a positive control strain (t339582) contained on each plate. As explained in Example 2 and in Table 6, OLS candidate enzymes within the library depicted in this Figure, and the positive control OLSs depicted in this Figure, were later found to contain a deletion in the nucleotide sequence encoding the OLS proteins, which led to the production of truncated proteins. Accordingly, all candidate OLS enzymes in this library, and the positive controls, were also tested independently in a new library containing only full-length OLS sequences, described in Example 3.

FIG. 9 is a graph showing olivetolic acid (OA) production by S. cerevisiae strains expressing OLS candidate enzymes. Peak areas obtained via LC/MS quantification were normalized to an internal standard for OA. Normalized peak areas were further normalized to a positive control strain (t339582) contained on each plate. As explained in Example 2 and in Table 6, OLS candidate enzymes within the library depicted in this Figure, and the positive control OLSs depicted in this Figure, were later found to contain a deletion in the nucleotide sequence encoding the OLS proteins, which led to the production of truncated proteins. Accordingly, all candidate OLS enzymes in this library, and the positive controls, were also tested independently in a new library containing only full-length OLS sequences, described in Example 3.

FIG. 10 is a graph showing normalized OA versus olivetol production by S. cerevisiae strains expressing OLS candidate enzymes. Peak areas obtained via LC/MS quantification for olivetol and OA were normalized to an internal standard for olivetol or OA, respectively. The regression line shown in FIG. 10 represents a 1:1 ratio of olivetol and olivetolic acid. Normalized peak areas were further normalized to positive control strain (t339582) contained on each plate. The strain t395094 demonstrated significantly increased olivetol production compared to the positive controls, while the strain t393974 showed enhanced production of OA over the positive control strains. The enhanced production of OA over olivetol by t393974 suggests that this enzyme possesses bifunctional PKS-PKC activity. As explained in Example 2 and in Table 6, OLS candidate enzymes within the library depicted in this Figure, and the positive control OLSs depicted in this Figure, were later found to contain a deletion in the nucleotide sequence encoding the OLS proteins, which led to the production of truncated proteins. Accordingly, all candidate OLS enzymes in this library, and the positive controls, were also tested independently in a new library containing only full-length OLS sequences, described in Example 3.

FIGS. 11A-11H show a sequence alignment of olivetol synthases (OLSs). An alignment of t394911 (SEQ ID NO: 28), t393974 (SEQ ID NO: 6), t393720 (SEQ ID NO: 27), t394336 (SEQ ID NO: 8), t393991 (SEQ ID NO: 7), t395011 (SEQ ID NO: 15), t339568 (SEQ ID NO: 5), t339579 (SEQ ID NO: 30), t339582 (SEQ ID NO: 31), t394457 (SEQ ID NO: 10), t394521 (SEQ ID NO: 11), t394436 (SEQ ID NO: 26), t395094 (SEQ ID NO: 17), t394087 (SEQ ID NO: 1), t395023 (SEQ ID NO: 29), t395103 (SEQ ID NO: 18), t394687 (SEQ ID NO: 2), t393835 (SEQ ID NO: 19), t394037 (SEQ ID NO: 22), t394905 (SEQ ID NO: 13), t393563 (SEQ ID NO: 4), t394981 (SEQ ID NO: 14), t394790 (SEQ ID NO: 12), t394797 (SEQ ID NO: 16), t394091 (SEQ ID NO: 21), t394043 (SEQ ID NO: 24), t394404 (SEQ ID NO: 25), t393495 (SEQ ID NO: 3), t394547 (SEQ ID NO: 9), t394115 (SEQ ID NO: 20), and t394279 (SEQ ID NO: 23) is shown. The sequence alignment was conducted using Clustal Omega. See, e.g., Chojnacki et al., Nucleic Acids Res. 2017 Jul. 3; 45(W1):W550-W553.

FIG. 12A-12B are graphs showing olivetol production (FIG. 12A) and olivetolic acid production (FIG. 12B) from S. cerevisiae strains expressing OLS candidate enzymes. Strains shown were determined to be hits from the primary screen of the library of OLS candidates screened in Example 3.

FIG. 13 is a graph showing olivetol production by S. cerevisiae strains expressing C. sativa OLS (CsOLS) point-mutant variants. Concentrations of olivetol in μg/L were determined via LC/MS quantification. The strain t405417 (having a T335C point mutation relative to the CsOLS set forth in SEQ ID NO: 5) demonstrated the highest olivetol production. Error bars represent the standard deviation of 4 independent measurements.

FIGS. 14A-14B are graphs showing olivetol production from S. cerevisiae strains expressing single point mutation and multiple point mutation variants based on a Cymbidium hybrid cultivar OLS template (ChOLS) (FIG. 14A) and a Corchorus olitorius OLS (CoOLS) template (FIG. 14B). Strains shown were screened in a secondary screen as described in Example 5. Olivetol titers were normalized to the mean olivetol titer produced by the positive control strain t527346 (FIG. 14A), and t606797 (FIG. 14B).

FIG. 15 is a graph showing olivetol production by a prototrophic S. cerevisiae strain expressing candidate OLS enzymes. Concentrations of olivetol in g/L were determined via LC/MS quantification. Performance of OLS candidate enzymes exhibiting higher olivetol production than C. sativa OLS positive controls is shown. The strains t485662, t485672, and t496073 demonstrated comparable olivetol production to the CsOLS T335C point-mutant positive control.

DETAILED DESCRIPTION

This disclosure provides methods for production of cannabinoids and cannabinoid precursors from fatty acid substrates using genetically modified host cells. Methods include heterologous expression of enzymes including acyl activating enzymes (AAE) and polyketide synthase enzymes (PKS) such as olivetol synthase enzymes (OLS). The disclosure describes identification of AAE and OLS enzymes that can be functionally expressed in eukaryotic (e.g., S. cerevisiae) and prokaryotic (E. coli) host cells such as S. cerevisiae and E. coli. As demonstrated in Example 1, novel AAE enzymes were identified that are capable of using hexanoate and butyrate as substrates to produce cannabinoid precursors. As demonstrated in Examples 2-3, novel OLS enzymes were identified that are capable of producing olivetol and olivetolic acid. Examples 4-6 further demonstrate enhanced production of olivetol and/or olivetolic acid by protein engineering of OLS enzymes. The novel enzymes described in this disclosure may be useful in increasing the efficiency and purity of cannabinoid production.

Definitions

While the following terms are believed to be well understood by one of ordinary skill in the art, the following definitions are set forth to facilitate explanation of the disclosed subject matter.

The term “a” or “an” refers to one or more of an entity, i.e., can identify a referent as plural. Thus, the terms “a” or “an,” “one or more” and “at least one” are used interchangeably in this application. In addition, reference to “an element” by the indefinite article “a” or “an” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there is one and only one of the elements.

The terms “microorganism” or “microbe” should be taken broadly. These terms are used interchangeably and include, but are not limited to, the two prokaryotic domains, Bacteria and Archaea, as well as certain eukaryotic fungi and protists. In some embodiments, the disclosure may refer to the “microorganisms” or “microbes” of lists/tables and figures present in the disclosure. This characterization can refer to not only the identified taxonomic genera of the tables and figures, but also the identified taxonomic species, as well as the various novel and newly identified or designed strains of any organism in the tables or figures. The same characterization holds true for the recitation of these terms in other parts of the specification, such as in the Examples.

The term “prokaryotes” is recognized in the art and refers to cells that contain no nucleus or other cell organelles. The prokaryotes are generally classified in one of two domains, the Bacteria and the Archaea.

“Bacteria” or “eubacteria” refers to a domain of prokaryotic organisms. Bacteria include at least 11 distinct groups as follows: (1) Gram-positive (gram+) bacteria, of which there are two major subdivisions: (a) high G+C group (Actinomycetes, Mycobacteria, Micrococcus, others) and (b) low G+C group (Bacillus, Clostridia, Lactobacillus, Staphylococci, Streptococci, Mycoplasmas); (2) Proteobacteria, e.g., Purple photosynthetic+non-photosynthetic Gram-negative bacteria (includes most “common” Gram-negative bacteria); (3) Cyanobacteria, e.g., oxygenic phototrophs; (4) Spirochetes and related species; (5) Planctomyces; (6) Bacteroides, Flavobacteria; (7) Chlamydia; (8) Green sulfur bacteria; (9) Green non-sulfur bacteria (also anaerobic phototrophs); (10) Radioresistant micrococci and relatives; and (11) Thermotoga and Thermosipho thermophiles.

The term “Archaea” refers to a taxonomic classification of prokaryotic organisms with certain properties that make them distinct from Bacteria in physiology and phylogeny.

The term “Cannabis” refers to a genus in the family Cannabaceae. Cannabis is a dioecious plant. Glandular structures located on female flowers of Cannabis, called trichomes, accumulate relatively high amounts of a class of terpeno-phenolic compounds known as phytocannabinoids (described in further detail below). Cannabis has conventionally been cultivated for production of fibre and seed (commonly referred to as “hemp-type”), or for production of intoxicants (commonly referred to as “drug-type”). In drug-type Cannabis, the trichomes contain relatively high amounts of tetrahydrocannabinolic acid (THCA), which can convert to tetrahydrocannabinol (THC) via a decarboxylation reaction, for example upon combustion of dried Cannabis flowers, to provide an intoxicating effect. Drug-type Cannabis often contains other cannabinoids in lesser amounts. In contrast, hemp-type Cannabis contains relatively low concentrations of THCA, often less than 0.3% THC by dry weight, accounting for the ability of THCA to convert to THC. Hemp-type Cannabis may contain non-THC and non-THCA cannabinoids, such as cannabidiolic acid (CBDA), cannabidiol (CBD), and other cannabinoids. Presently, there is a lack of consensus regarding the taxonomic organization of the species within the genus. Unless context dictates otherwise, the term “Cannabis” is intended to include all putative species within the genus, such as, without limitation, Cannabis sativa, Cannabis indica, and Cannabis ruderalis and without regard to whether the Cannabis is hemp-type or drug-type.

The term “cyclase activity” in reference to a polyketide synthase (PKS) enzyme (e.g., an olivetol synthase (OLS) enzyme) or a polyketide cyclase (PKC) enzyme (e.g., an olivetolic acid cyclase (OAC) enzyme), refers to the activity of catalyzing the cyclization of an oxo fatty acyl-CoA (e.g., 3,5,7-trioxododecanoyl-COA, 3,5,7-trioxodecanoyl-COA) to the corresponding intramolecular cyclization product (e.g., olivetolic acid, divarinic acid). In some embodiments, the PKS catalyzes the C2-C7 aldol condensation of an acyl-COA with three additional ketide moieties added thereto.

A “cytosolic” or “soluble” enzyme refers to an enzyme that is predominantly localized (or predicted to be localized) in the cytosol of a host cell.

A “eukaryote” is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota. The defining feature that sets eukaryotic cells apart from prokaryotic cells (i.e., bacteria and archaea) is that they have membrane-bound organelles, especially the nucleus, which contains the genetic material, and is enclosed by the nuclear envelope.

The term “host cell” refers to a cell that can be used to express a polynucleotide, such as a polynucleotide that encodes an enzyme used in biosynthesis of cannabinoids or cannabinoid precursors. The terms “genetically modified host cell,” “recombinant host cell,” and “recombinant strain” are used interchangeably and refer to host cells that have been genetically modified by, e.g., cloning and transformation methods, or by other methods known in the art (e.g., selective editing methods, such as CRISPR). Thus, the terms include a host cell (e.g., bacterial cell, yeast cell, fungal cell, insect cell, plant cell, mammalian cell, human cell, etc.) that has been genetically altered, modified, or engineered, so that it exhibits an altered, modified, or different genotype and/or phenotype, as compared to the naturally-occurring cell from which it was derived. It is understood that in some embodiments, the terms refer not only to the particular recombinant host cell in question, but also to the progeny or potential progeny of such a host cell.

The term “control host cell,” or the term “control” when used in relation to a host cell, refers to an appropriate comparator host cell for determining the effect of a genetic modification or experimental treatment. In some embodiments, the control host cell is a wild type cell. In other embodiments, a control host cell is genetically identical to the genetically modified host cell, except for the genetic modification(s) differentiating the genetically modified or experimental treatment host cell. In some embodiments, the control host cell has been genetically modified to express a wild type or otherwise known variant of an enzyme being tested for activity in other test host cells.

The term “heterologous” with respect to a polynucleotide, such as a polynucleotide comprising a gene, is used interchangeably with the term “exogenous” and the term “recombinant” and refers to a polynucleotide that has been artificially supplied to a biological system, a polynucleotide that has been modified within a biological system, or a polynucleotide whose expression or regulation has been manipulated within a biological system. A heterologous polynucleotide that is introduced into or expressed in a host cell may be a polynucleotide that comes from a different organism or species than the host cell, or may be a synthetic polynucleotide, or may be a polynucleotide that is also endogenously expressed in the same organism or species as the host cell. For example, a polynucleotide that is endogenously expressed in a host cell may be considered heterologous when it is situated non-naturally in the host cell; expressed recombinantly in the host cell, either stably or transiently; modified within the host cell; selectively edited within the host cell; expressed in a copy number that differs from the naturally occurring copy number within the host cell; or expressed in a non-natural way within the host cell, such as by manipulating regulatory regions that control expression of the polynucleotide. In some embodiments, a heterologous polynucleotide is a polynucleotide that is endogenously expressed in a host cell but whose expression is driven by a promoter that does not naturally regulate expression of the polynucleotide. In other embodiments, a heterologous polynucleotide is a polynucleotide that is endogenously expressed in a host cell and whose expression is driven by a promoter that does naturally regulate expression of the polynucleotide, but the promoter or another regulatory region is modified. In some embodiments, the promoter is recombinantly activated or repressed. For example, gene-editing based techniques may be used to regulate expression of a polynucleotide, including an endogenous polynucleotide, from a promoter, including an endogenous promoter. See, e.g., Chavez et al., Nat Methods. 2016 July; 13(7): 563-567. A heterologous polynucleotide may comprise a wild-type sequence or a mutant sequence as compared with a reference polynucleotide sequence.

The term “at least a portion” or “at least a fragment” of a nucleic acid or polypeptide means a portion having the minimal size characteristics of such sequences, or any larger fragment of the full length molecule, up to and including the full length molecule. A fragment of a polynucleotide of the disclosure may encode a biologically active portion of an enzyme, such as a catalytic domain. A biologically active portion of a genetic regulatory element may comprise a portion or fragment of a full length genetic regulatory element and have the same type of activity as the full length genetic regulatory element, although the level of activity of the biologically active portion of the genetic regulatory element may vary compared to the level of activity of the full length genetic regulatory element.

A coding sequence and a regulatory sequence are said to be “operably joined” or “operably linked” when the coding sequence and the regulatory sequence are covalently linked and the expression or transcription of the coding sequence is under the influence or control of the regulatory sequence. If the coding sequence is to be translated into a functional protein, the coding sequence and the regulatory sequence are said to be operably joined if induction of a promoter in the 5′ regulatory sequence results in transcription of the coding sequence and if the nature of the linkage between the coding sequence and the regulatory sequence does not (1) result in the introduction of a frame-shift mutation, (2) interfere with the ability of the promoter region to direct the transcription of the coding sequence, or (3) interfere with the ability of the corresponding RNA transcript to be translated into a protein.

The term “volumetric productivity” or “production rate” refers to the amount of product formed per volume of medium per unit of time. Volumetric productivity can be reported in gram per liter per hour (g/L/h).

The term “specific productivity” of a product refers to the rate of formation of the product normalized by unit volume or mass or biomass and has the physical dimension of a quantity of substance per unit time per unit mass or volume [M·T⁻¹·M⁻¹ or M·T⁻¹·L⁻³, where M is mass or moles, T is time, L is length].

The term “biomass specific productivity” refers to the specific productivity in gram product per gram of cell dry weight (CDW) per hour (g/g CDW/h) or in mmol of product per gram of cell dry weight (CDW) per hour (mmol/g CDW/h). Using the relation of CDW to OD600 for the given microorganism, specific productivity can also be expressed as gram product per liter culture medium per optical density of the culture broth at 600 nm (OD) per hour (g/L/h/OD). Also, if the elemental composition of the biomass is known, biomass specific productivity can be expressed in mmol of product per C-mole (carbon mole) of biomass per hour (mmol/C-mol/h).

The term “yield” refers to the amount of product obtained per unit weight of a certain substrate and may be expressed as g product per g substrate (g/g) or moles of product per mole of substrate (mol/mol). Yield may also be expressed as a percentage of the theoretical yield. “Theoretical yield” is defined as the maximum amount of product that can be generated per a given amount of substrate as dictated by the stoichiometry of the metabolic pathway used to make the product and may be expressed as g product per g substrate (g/g) or moles of product per mole of substrate (mol/mol).

The term “titer” refers to the strength of a solution or the concentration of a substance in solution. For example, the titer of a product of interest (e.g., small molecule, peptide, synthetic compound, fuel, alcohol, etc.) in a fermentation broth is described as g of product of interest in solution per liter of fermentation broth or cell-free broth (g/L) or as g of product of interest in solution per kg of fermentation broth or cell-free broth (g/Kg).

The term “total titer” refers to the sum of all products of interest produced in a process, including but not limited to the products of interest in solution, the products of interest in gas phase if applicable, and any products of interest removed from the process and recovered relative to the initial volume in the process or the operating volume in the process. For example, the total titer of products of interest (e.g., small molecule, peptide, synthetic compound, fuel, alcohol, etc.) in a fermentation broth is described as g of products of interest in solution per liter of fermentation broth or cell-free broth (g/L) or as g of products of interest in solution per kg of fermentation broth or cell-free broth (g/Kg).

The term “amino acid” refers to organic compounds that comprise an amino group, —NH2, and a carboxyl group, —COOH. The term “amino acid” includes both naturally occurring and unnatural amino acids. Nomenclature for the twenty common amino acids is as follows: alanine (ala or A); arginine (arg or R); asparagine (asn or N); aspartic acid (asp or D); cysteine (cys or C); glutamine (gln or Q); glutamic acid (glu or E); glycine (gly or G); histidine (his or H); isoleucine (ile or I); leucine (leu or L); lysine (lys or K); methionine (met or M); phenylalanine (phe or F); proline (pro or P); serine (ser or S); threonine (thr or T); tryptophan (trp or W); tyrosine (tyr or Y); and valine (val or V).

A “partially unsaturated” ring system is further intended to encompass rings having multiple sites of unsaturation but is not intended to include aromatic groups (e.g., aryl or heteroaryl groups) as defined in this application. Likewise, “saturated” refers to a group that does not contain a double or triple bond, i.e., contains all single bonds.

The term “optionally substituted” means substituted or unsubstituted.

Alkyl, alkenyl, alkynyl, carbocyclyl, heterocyclyl, aryl, and heteroaryl groups are optionally substituted (e.g., “substituted” or “unsubstituted” alkyl, “substituted” or “unsubstituted” alkenyl, “substituted” or “unsubstituted” alkynyl, “substituted” or “unsubstituted” carbocyclyl, “substituted” or “unsubstituted” heterocyclyl, “substituted” or “unsubstituted” aryl or “substituted” or “unsubstituted” heteroaryl group). In general, the term “substituted,” whether preceded by the term “optionally” or not, means that at least one hydrogen present on a group (e.g., a carbon or nitrogen atom) is replaced with a permissible substituent, e.g., a substituent which upon substitution results in a stable compound, e.g., a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction. Unless otherwise indicated, a “substituted” group has a substituent at one or more substitutable positions of the group, and when more than one position in any given structure is substituted, the substituent is either the same or different at each position. The term “substituted” is contemplated to include substitution with all permissible substituents of organic compounds, any of the substituents described in this application that results in the formation of a stable compound. The present invention contemplates any and all such combinations in order to arrive at a stable compound. For purposes of this invention, heteroatoms such as nitrogen may have hydrogen substituents and/or any suitable substituent as described in this application which satisfy the valencies of the heteroatoms and results in the formation of a stable moiety.

A “counterion” or “anionic counterion” is a negatively charged group associated with a positively charged group in order to maintain electronic neutrality. An anionic counterion may be monovalent (i.e., including one formal negative charge). An anionic counterion may also be multivalent (i.e., including more than one formal negative charge), such as divalent or trivalent. Exemplary counterions include halide ions (e.g., F⁻, Cl⁻, Br⁻, I⁻), NO₃ ⁻, ClO₄ ⁻, OH⁻, H₂PO₄ ⁻, HCO₃ ⁻, HSO₄ ⁻, sulfonate ions (e.g., methansulfonate, trifluoromethanesulfonate, p-toluenesulfonate, benzenesulfonate, 10-camphor sulfonate, naphthalene-2-sulfonate, naphthalene-1-sulfonic acid-5-sulfonate, ethan-1-sulfonic acid-2-sulfonate, and the like), carboxylate ions (e.g., acetate, propanoate, benzoate, glycerate, lactate, tartrate, glycolate, gluconate, and the like), BF₄ ⁻, PF₄ ⁻, PF⁻, AsF⁻, SbF⁻, B[3,5-(CF₃)₂C₆H₃]₄ ⁻, B(C₆F₅)₄ ⁻, BPh₄ ⁻, Al(OC(CF₃)₃)₄ ⁻, and carborane anions (e.g., CB₁₁H₁₂ ⁻ or (HCB₁₁Me₅Br₆)⁻). Exemplary counterions which may be multivalent include CO₃ ²⁻, HPO₄ ²⁻, PO₄ ³⁻, B₄O₇ ²⁻, SO₄ ²⁻, S₂O₃ ²⁻, carboxylate anions (e.g., tartrate, citrate, fumarate, maleate, malate, malonate, gluconate, succinate, glutarate, adipate, pimelate, suberate, azelate, sebacate, salicylate, phthalates, aspartate, glutamate, and the like), and carboranes.

The term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated by reference. Pharmaceutically acceptable salts of the compounds disclosed in this application include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N⁺(C₁₋₄ alkyl)₄ ⁻ salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.

The term “solvate” refers to forms of a compound that are associated with a solvent, usually by a solvolysis reaction. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, DMSO, THF, diethyl ether, and the like. The compounds of Formula (1), (9), (10), and (11) may be prepared, e.g., in crystalline form, and may be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In certain instances, the solvate will be capable of isolation, for example, when one or more solvent molecules are incorporated in the crystal lattice of a crystalline solid. “Solvate” encompasses both solution-phase and isolable solvates. Representative solvates include hydrates, ethanolates, and methanolates.

The term “hydrate” refers to a compound that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, a hydrate of a compound may be represented, for example, by the general formula R.x H₂O, wherein R is the compound and wherein x is a number greater than 0. A given compound may form more than one type of hydrates, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R.0.5 H₂O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R.2 H₂O) and hexahydrates (R.6 H₂O)).

The term “tautomers” refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of 7 electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro-forms of phenylnitromethane, which are likewise formed by treatment with acid or base. Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.

It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers.” Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers.”

Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers.” When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and described by the R- and S-sequencing rules of Cahn and Prelog. An enantiomer can also be characterized by the manner in which the molecule rotates the plane of polarized light, and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either an individual enantiomer or as a mixture of enantiomers. A mixture containing equal proportions of the enantiomers is called a “racemic mixture.”

The term “co-crystal” refers to a crystalline structure comprising at least two different components (e.g., a compound described in this application and an acid), wherein each of the components is independently an atom, ion, or molecule. In certain embodiments, none of the components is a solvent. In certain embodiments, at least one of the components is a solvent. A co-crystal of a compound and an acid is different from a salt formed from a compound and the acid. In the salt, a compound described in this application is complexed with the acid in a way that proton transfer (e.g., a complete proton transfer) from the acid to a compound described in this application easily occurs at room temperature. In the co-crystal, however, a compound described in this application is complexed with the acid in a way that proton transfer from the acid to a compound described in this application does not easily occur at room temperature. In certain embodiments, in the co-crystal, there is no proton transfer from the acid to a compound described in this application. In certain embodiments, in the co-crystal, there is partial proton transfer from the acid to a compound described in this application. Co-crystals may be useful to improve the properties (e.g., solubility, stability, and ease of formulation) of a compound described in this application.

The term “polymorphs” refers to a crystalline form of a compound (or a salt, hydrate, or solvate thereof) in a particular crystal packing arrangement. All polymorphs of the same compound have the same elemental composition. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Recrystallization solvent, rate of crystallization, storage temperature, and other factors may cause one crystal form to dominate. Various polymorphs of a compound can be prepared by crystallization under different conditions.

The term “prodrug” refers to compounds, including derivatives of the compounds of Formula (X), (8), (9), (10), or (11), that have cleavable groups and become by solvolysis or under physiological conditions the compounds of Formula (X), (8), (9), (10), or (11) and that are pharmaceutically active in vivo. The prodrugs may have attributes such as, without limitation, solubility, bioavailability, tissue compatibility, or delayed release in a mammalian organism. Examples include, but are not limited to, derivatives of compounds described in this application, including derivatives formed from glycosylation of the compounds described in this application (e.g., glycoside derivatives), carrier-linked prodrugs (e.g., ester derivatives), bioprecursor prodrugs (a prodrug metabolized by molecular modification into the active compound), and the like. Non-limiting examples of glycoside derivatives are disclosed in and incorporated by reference from WO2018208875 and US20190078168. Non-limiting examples of ester derivatives are disclosed in and incorporated by reference from US20170362195.

Other derivatives of the compounds of this invention have activity in both their acid and acid derivative forms, but the acid sensitive form often offers advantages of solubility, bioavailability, tissue compatibility, or delayed release in a mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well known to practitioners of the art, such as, for example, esters prepared by reaction of the parent acid with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a substituted or unsubstituted amine, or acid anhydrides, or mixed anhydrides. Simple aliphatic or aromatic esters, amides, and anhydrides derived from acidic groups pendant on the compounds of this invention are particular prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy)alkyl esters or ((alkoxycarbonyl)oxy)alkylesters. C₁-C₈ alkyl, C₂-C₈ alkenyl, C₂-C₈ alkynyl, aryl, C₇-C₁₂ substituted aryl, and C₇-C₁₂ arylalkyl esters of the compounds of Formula (X), (8), (9), (10), or (11) may be preferred. Cannabinoids

In some embodiments, non-limiting examples of the acyl-CoA scaffold described in step (a) include hexanoyl-CoA and butyryl-CoA. In some embodiments, non-limiting examples of the product of step (b) or a derivative of the product of step (b) include olivetolic acid and divarinic acid.

In some embodiments, cannabinoids of the present disclosure comprise cannabinoid receptor ligands. Cannabinoid receptors are a class of cell membrane receptors in the G protein-coupled receptor superfamily. Cannabinoid receptors include the CB₁ receptor and the CB₂ receptor. In some embodiments, cannabinoid receptors comprise GPR18, GPR55, and PPAR. (See Bram et al. “Activation of GPR18 by cannabinoid compounds: a tale of biased agonism” Br J Pharmcol v171 (16) (2014); Shi et al. “The novel cannabinoid receptor GPR55 mediates anxiolytic-like effects in the medial orbital cortex of mice with acute stress” Molecular Brain 10, No. 38 (2017); and O'Sullvan, Elizabeth. “An update on PPAR activation by cannabinoids” Br J Pharmcol v. 173(12) (2016)).

In some embodiments, cannabinoids comprise endocannabinoids, which are substances produced within the body, and phytocannabinoids, which are cannabinoids that are naturally produced by plants of genus Cannabis. In some embodiments, phytocannabinoids comprise the acidic and decarboxylated acid forms of the naturally-occurring plant-derived cannabinoids, and their synthetic and biosynthetic equivalents.

Over 94 phytocannabinoids have been identified to date (Berman, Paula, et al. “A new ESI-LC/MS approach for comprehensive metabolic profiling of phytocannabinoids in Cannabis.” Scientific reports 8.1 (2018): 14280; El-Alfy et al., 2010, “Antidepressant-like effect of delta-9-tetrahydrocannabinol and other cannabinoids isolated from Cannabis sativa L”, Pharmacology Biochemistry and Behavior 95 (4): 434-42; Rudolf Brenneisen, 2007, Chemistry and Analysis of Phytocannabinoids, each of which is incorporated by reference in this application in its entirety). In some embodiments, cannabinoids comprise Δ⁹-tetrahydrocannabinol (THC) type (e.g., (−)-trans-delta-9-tetrahydrocannabinol or dronabinol, (+)-trans-delta-9-tetrahydrocannabinol, (−)-cis-delta-9-tetrahydrocannabinol, or (+)-cis-delta-9-tetrahydrocannabinol), cannabidiol (CBD) type, cannabigerol (CBG) type, cannabichromene (CBC) type, cannabicyclol (CBL) type, cannabinodiol (CBND) type, or cannabitriol (CBT) type cannabinoids, or any combination thereof (see, e.g., R Pertwee, ed, Handbook of Cannabis (Oxford, UK: Oxford University Press, 2014)), which is incorporated by reference in this application in its entirety).

In some embodiments, rare cannabinoids include CBGA, CBGVA, THCVA, CBDVA, CBCVA, and CBCA. In some embodiments, rare cannabinoids are cannabinoids that are not THCA, THC, CBDA or CBD.

A cannabinoid described in this application can also be a non-rare cannabinoid.

Biosynthesis of Cannabinoids and Cannabinoid Precursors

Aspects of the present disclosure provide tools, sequences, and methods for the biosynthetic production of cannabinoids in host cells. In some embodiments, the present disclosure teaches expression of enzymes that are capable of producing cannabinoids by biosynthesis.

As anon-limiting example, one or more of the enzymes depicted in FIG. 2 may be used to produce a cannabinoid or cannabinoid precursor of interest. FIG. 1 shows a cannabinoid biosynthesis pathway for the most abundant phytocannabinoids found in Cannabis. See also, de Meijer et al.

It should be appreciated that a precursor substrate for use in cannabinoid biosynthesis is generally selected based on the cannabinoid of interest. Non-limiting examples of cannabinoid precursors include compounds of Formulae 1-8 in FIG. 2. In some embodiments, polyketides, including compounds of Formula 5, could be prenylated.

The chain length of a precursor substrate can be from C1-C40. Those substrates can have any degree and any kind of branching or saturation or chain structure, including, without limitation, aliphatic, alicyclic, and aromatic. In addition, they may include any functional groups including hydroxy, halogens, carbohydrates, phosphates, methyl-containing or nitrogen-containing functional groups.

For example, FIG. 3 shows a non-exclusive set of putative precursors for the cannabinoid pathway. Aliphatic carboxylic acids including four to eight total carbons (“C4”-“C8” in FIG. 3) and up to 10-12 total carbons with either linear or branched chains may be used as precursors for the heterologous pathway. Non-limiting examples include methanoic acid, butyric acid, pentanoic acid, hexanoic acid, heptanoic acid, isovaleric acid, octanoic acid, and decanoic acid. Additional precursors may include ethanoic acid and propanoic acid. In some embodiments, in addition to acids, the ester, salt, and acid forms may all be used as substrates. Substrates may have any degree and any kind of branching, saturation, and chain structure, including, without limitation, aliphatic, alicyclic, and aromatic. In addition, they may include any functional modifications or combination of modifications including, without limitation, halogenation, hydroxylation, amination, acylation, alkylation, phenylation, and/or installation of pendant carbohydrates, phosphates, sulfates, heterocycles, or lipids, or any other functional groups.

Substrates for any of the enzymes disclosed in this application may be provided exogenously or may be produced endogenously by a host cell. In some embodiments, the cannabinoids are produced from a glucose substrate, so that compounds of Formula 1 shown in FIG. 2 and CoA precursors are synthesized by the cell. In other embodiments, a precursor is fed into the reaction. In some embodiments, a precursor is a compound selected from Formulae 1-8 in FIG. 2.

Cannabinoids produced by methods disclosed in this application include rare cannabinoids. Due to the low concentrations at which rare cannabinoids occur in nature, producing industrially significant amounts of isolated or purified rare cannabinoids from the Cannabis plant may become prohibitive due to, e.g., the large volumes of Cannabis plants, and the large amounts of space, labor, time, and capital requirements to grow, harvest, and/or process the plant materials. The disclosure provided in this application represents a potentially efficient method for producing high yields of cannabinoids, including rare cannabinoids.

Cannabinoids produced by the disclosed methods also include non-rare cannabinoids. Without being bound by a particular theory, the methods described in this application may be advantageous compared with traditional plant-based methods for producing non-rare cannabinoids. For example, methods provided in this application represent potentially efficient means for producing consistent and high yields of non-rare cannabinoids. With traditional methods of cannabinoid production, in which cannabinoids are harvested from plants, maintaining consistent and uniform conditions, including airflow, nutrients, lighting, temperature, and humidity, can be difficult. For example, with plant-based methods, there can be microclimates created by branching, which can lead to inconsistent yields and by-product formation. In some embodiments, the methods described in this application are more efficient at producing a cannabinoid of interest as compared to harvesting cannabinoids from plants. For example, with plant-based methods, seed-to-harvest can take up to half a year, while cutting-to-harvest usually takes about 4 months. Additional steps including drying, curing, and extraction are also usually needed with plant-based methods. In contrast, in some embodiments, the fermentation-based methods described in this application only take about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 days. In some embodiments, the fermentation-based methods described in this application only take about 3-5 days. In some embodiments, the fermentation-based methods described in this application only take about 5 days. In some embodiments, the methods provided in this application reduce the amount of security needed to comply with regulatory standards. For example, a smaller secured area may be needed to be monitored and secured to practice the methods described in this application as compared to the cultivation of plants. In some embodiments, the methods described in this application are advantageous over plant-sourced cannabinoids.

In other embodiments, an AAE exhibits activity on at least two of hexanoic acid, butyric acid, isovaleric acid, octanoic acid, and decanoic acid. AAE enzymes were identified herein that exhibited activity on butyrate and/or hexanoate (FIGS. 5 and 6). Activity on butyrate was unexpected in view of disclosure in Carvalho et al. “Designing Microorganisms for Heterologous Biosynthesis of Cannabinoids” (2017) FEMS Yeast Research June 1; 17(4).

In some embodiments, a control is a host cell that does not express a heterologous gene encoding an AAE.

Polyketide Synthases (PKS)

A host cell described in this application may comprise a PKS. As used in this application, a “PKS” refers to an enzyme that is capable of producing a polyketide. In certain embodiments, a PKS converts a compound of Formula (2) to a compound of Formula (4), (5), and/or (6). In certain embodiments, a PKS converts a compound of Formula (2) to a compound of Formula (4). In certain embodiments, a PKS converts a compound of Formula (2) to a compound of Formula (5). In certain embodiments, a PKS converts a compound of Formula (2) to a compound of Formula (4) and/or (5). In certain embodiments, a PKS converts a compound of Formula (2) to a compound of Formula (5) and/or (6).

In some embodiments, a PKS is a tetraketide synthase (TKS). In certain embodiments, a PKS is an olivetol synthase (OLS). As used in this application, an “OLS” refers to an enzyme that is capable of using a substrate of Formula (2a) to form a compound of Formula (4a), (5a) and/or (6a) as shown in FIG. 1. In some embodiments, an OLS catalyzes the formation of olivetol (Formula (5a)). In some embodiments, an olivetol synthase (OLS) catalyzes the formation of olivetol with minimal production of 3,5,7-trioxoalkanoyl-CoA and/or olivetolic acid. In some instances, an OLS that is capable of catalyzing the formation of olivetol may be useful in providing olivetol as a substrate for a prenyltransferase. As a non-limiting example, NphB can use olivetol as reactant. See, e.g., Kumano et al., Bioorg Med Chem. 2008 Sep. 1; 16(17): 8117-8126.

In certain embodiments, a PKS is a divarinic acid synthase (DVS).

A non-limiting example of an OLS is provided by UniProtKB—B1Q2B6 from C. sativa. In C. sativa, this OLS uses hexanoyl-CoA and malonyl-CoA as substrates to form 3,5,7-trioxododecanoyl-CoA. OLS (e.g., UniProtKB—B1Q2B6) in combination with olivetolic acid cyclase (OAC) produces olivetolic acid (OA) in C. sativa.

The amino acid sequence of UniProtKB—B1Q2B6 is:

(SEQ ID NO: 5) MNHLRAEGPASVLAIGTANPENILLQDEFPDYYFRVTKSEHMTQLKEKFR KICDKSMIRKRNCFLNEEHLKQNPRLVEHEMQTLDARQDMLVVEVPKLGK DACAKAIKEWGQPKSKITHLIFTSASTTDMPGADYHCAKLLGLSPSVKRV MMYQLGCYGGGTVLRIAKDIAENNKGARVLAVCCDIMACLFRGPSESDLE LLVGQAIFGDGAAAVIVGAEPDESVGERPIFELVSTGQTILPNSEGTIGG HIREAGLIFDLHKDVPMLISNNIEKCLIEAFTPIGISDWNSIFWITHPGG KAILDKVEEKLHLKSDKFVDSRHVLSEHGNMSSSTVLFVMDELRKRSLEE GKSTTGDGFEWGVLFGFGPGLTVERVVVRSVPIKY.

Structurally, an OLS comprises a triad of conserved residues, which have been implicated as catalytic residues. This triad of conserved residues may be referred to as a catalytic triad. See, e.g., Taura et al., FEBS Letters 583 (2009) 2061-2066. The catalytic triad of UniProtKB—B1Q2B6 (SEQ ID NO: 5) comprises C157, H297, and N330. One of ordinary skill in the art would be able to identify corresponding catalytic residues in other PKSs, including OLSs, by aligning the amino acid sequence of interest with UniProtKB—B1Q2B6. A PKS, including an OLS, may comprise the amino acid C at a residue corresponding to position 157 in SEQ ID NO: 5, the amino acid H at a residue corresponding to position 297 in SEQ ID NO: 5, and the amino acid N at a residue corresponding to residue 330 in SEQ ID NO: 5. As a non-limiting example, the residues corresponding to positions 157, 297, and 330 in SEQ ID NO: 5 are C164, H304, and N337, respectively in SEQ ID NO: 6. Similarly, the residues corresponding to positions 157, 297, and 330 in SEQ ID NO: 5 are C164, H304, and N337, respectively, in SEQ ID NO: 7.

The active site of a PKS may be defined by generating the three-dimensional structure of the PKS and identifying the residues within a particular distance of any of the residues within the catalytic triad and/or within a particular distance of a docked substrate within the PKS (e.g., a compound of Formula (2)). A substrate docks or binds in the substrate binding pocket of a PKS. The substrate binding pocket may comprise the active site of the PKS. As a non-limiting example, the structure of a PKS may be generated using ROSETTA software. See, e.g., Kaufmann et al., Biochemistry 2010, 49, 2987-2998.

As one of ordinary skill in the art would appreciate a PKS, such as an OLS, could be obtained from any source, including naturally occurring sources and synthetic sources (e.g., a non-natually occurring PKS). In some embodiments a PKS is from Cannabis. In some embodiments a PKS is from Dictyostelium. Non-limiting examples of PKS enzymes may be found in U.S. Pat. No. 6,265,633; WO2019/202510; WO 2018/148848 A1; WO 2018/148849 A1; and US 2018/155748 (granted as U.S. Pat. No. 10,435,727), which are incorporated by reference in this application in their entireties. For example, PKSs include SEQ ID NO: 2 from WO2019/202510, SEQ ID NO: 9 from WO2019/202510, SEQ ID NO: 37 from WO 2018/148848 A1, SEQ ID NO: 38 from WO 2018/148848 A1, SEQ ID NO: 9 from WO 2018/148849 A1, SEQ ID NO: 10 from WO 2018/148849 A1, SEQ ID NO: 13 from WO 2018/148849 A1; and SEQ ID NO: 35 from U.S. Pat.

In certain embodiments, polyketide synthases can use hexanoyl-CoA or any acyl-CoA (or a product of Formula (2)):

and three malonyl-CoAs as substrates to form 3,5,7-trioxododecanoyl-CoA or other 3,5,7-trioxo-acyl-CoA derivatives; or to form a compound of Formula (4):

wherein R is hydrogen, optionally substituted acyl, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, or optionally substituted aryl; depending on substrate. R is as defined in this application. In some embodiments, R is a C2-C6 optionally substituted alkyl. In some embodiments, R is a propyl or pentyl. In some embodiments, R is pentyl. In some embodiments, R is propyl. A PKS may also bind isovaleryl-CoA, octanoyl-CoA, hexanoyl-CoA, and butyryl-CoA. In some embodiments, a PKS is capable of catalyzing the formation of a 3,5,7-trioxoalkanoyl-CoA (e.g. 3,5,7-trioxododecanoyl-CoA). In some embodiments, an OLS is capable of catalyzing the formation of a 3,5,7-trioxoalkanoyl-CoA (e.g. 3,5,7-trioxododecanoyl-CoA).

In some embodiments, a PKS uses a substrate of Formula (2) to form a compound of Formula (4):

wherein R is unsubstituted pentyl.

A recombinant host cell that expresses a heterologous gene encoding an PKS described herein may be capable of producing at least 1% (e.g., at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 100%, at least 125%, at least 150%, at least 175%, at least 200%, at least 300%, at least 400%, at least 500%, at least 600%, at least 700%, at least 800%, at least 900%, or at least 1,000%) more of a product (e.g., a compound of Formula (4), (5), and/or (6)) relative to a control. In some embodiments, a compound of Formula (4) is a compound of Formula (4a), a compound of Formula (5) is a compound of Formula (5a), and a compound of Formula (6) is a compound of Formula (6a). In some embodiments, a control is a recombinant host cell that expresses a heterologous gene encoding UniProtKB—B1Q2B6. In some embodiments, a control is a recombinant host cell that expresses a heterologous gene encoding a wild-type PKS.

A recombinant host cell that expresses a heterologous gene encoding an PKS described herein may be capable of producing at least 0.5 mg/L, at least 1 mg/L, at least 1.5 mg/L, at least 2 mg/L, at least 2.5 mg/L, at least 3 mg/L, at least 3.5 mg/L, at least 4 mg/L, at least 4.5 mg/L, at least 5 mg/L, at least 5.5 mg/L, at least 6 mg/L, at least 6.5 mg/L, at least 7 mg/L, at least 7.5 mg/L, at least 8 mg/L, at least 8.5 mg/L, at least 9 mg/L, at least 9.5 mg/L, at least 10 mg/L, at least 10.5 mg/L, at least 11 mg/L, at least 11.5 mg/L, at least 12 mg/L, at least 12.5 mg/L, at least 13 mg/L, at least 13.5 mg/L, at least 14 mg/L, at least 14.5 mg/L, at least 15 mg/L, at least 15.5 mg/L, at least 16 mg/L, at least 16.5 mg/L, at least 17 mg/L, at least 17.5 mg/L, at least 18 mg/L, at least 18.5 mg/L, at least 19 mg/L, at least 19.5 mg/L, at least 20 mg/L, at least 20.5 mg/L, at least 21 mg/L, at least 21.5 mg/L, at least 22 mg/L, at least 22.5 mg/L, at least 23 mg/L, at least 23.5 mg/L, at least 24 mg/L, at least 24.5 mg/L, at least 25 mg/L, at least 25.5 mg/L, at least 26 mg/L, at least 26.5 mg/L, at least 27 mg/L, at least 27.5 mg/L, at least 28 mg/L, at least 28.5 mg/L, at least 29 mg/L, at least 29.5 mg/L, at least 30 mg/L, at least 30.5 mg/L, at least 31 mg/L, at least 31.5 mg/L, at least 32 mg/L, at least 32.5 mg/L, at least 33 mg/L, at least 33.5 mg/L, at least 34 mg/L, at least 34.5 mg/L, at least 35 mg/L, at least 35.5 mg/L, at least 36 mg/L, at least 36.5 mg/L, at least 37 mg/L, at least 37.5 mg/L, at least 38 mg/L, at least 38.5 mg/L, at least 39 mg/L, at least 39.5 mg/L, at least 40 mg/L, at least 40.5 mg/L, at least 41 mg/L, at least 41.5 mg/L, at least 42 mg/L, at least 42.5 mg/L, at least 43 mg/L, at least 43.5 mg/L, at least 44 mg/L, at least 44.5 mg/L, at least 45 mg/L, at least 45.5 mg/L, at least 46 mg/L, at least 46.5 mg/L, at least 47 mg/L, at least 47.5 mg/L, at least 48 mg/L, at least 48.5 mg/L, at least 49 mg/L, at least 49.5 mg/L, at least 50 mg/L, at least 50.5 mg/L, at least 51 mg/L, at least 51.5 mg/L, at least 52 mg/L, at least 52.5 mg/L, at least 53 mg/L, at least 53.5 mg/L, at least 54 mg/L, at least 54.5 mg/L, at least 55 mg/L, at least 55.5 mg/L, at least 56 mg/L, at least 56.5 mg/L, at least 57 mg/L, at least 57.5 mg/L, at least 58 mg/L, at least 58.5 mg/L, at least 59 mg/L, at least 59.5 mg/L, at least 60 mg/L, at least 60.5 mg/L, at least 61 mg/L, at least 61.5 mg/L, at least 62 mg/L, at least 62.5 mg/L, at least 63 mg/L, at least 63.5 mg/L, at least 64 mg/L, at least 64.5 mg/L, at least 65 mg/L, at least 65.5 mg/L, at least 66 mg/L, at least 66.5 mg/L, at least 67 mg/L, at least 67.5 mg/L, at least 68 mg/L, at least 68.5 mg/L, at least 69 mg/L, at least 69.5 mg/L, at least 70 mg/L, at least 70.5 mg/L, at least 71 mg/L, at least 71.5 mg/L, at least 72 mg/L, at least 72.5 mg/L, at least 73 mg/L, at least 73.5 mg/L, at least 74 mg/L, at least 74.5 mg/L, at least 75 mg/L, at least 75.5 mg/L, at least 76 mg/L, at least 76.5 mg/L, at least 77 mg/L, at least 77.5 mg/L, at least 78 mg/L, at least 78.5 mg/L, at least 79 mg/L, at least 79.5 mg/L, at least 80 mg/L, at least 80.5 mg/L, at least 81 mg/L, at least 81.5 mg/L, at least 82 mg/L, at least 82.5 mg/L, at least 83 mg/L, at least 83.5 mg/L, at least 84 mg/L, at least 84.5 mg/L, at least 85 mg/L, at least 85.5 mg/L, at least 86 mg/L, at least 86.5 mg/L, at least 87 mg/L, at least 87.5 mg/L, at least 88 mg/L, at least 88.5 mg/L, at least 89 mg/L, at least 89.5 mg/L, at least 90 mg/L, at least 90.5 mg/L, at least 91 mg/L, at least 91.5 mg/L, at least 92 mg/L, at least 92.5 mg/L, at least 93 mg/L, at least 93.5 mg/L, at least 94 mg/L, at least 94.5 mg/L, at least 95 mg/L, at least 95.5 mg/L, at least 96 mg/L, at least 96.5 mg/L, at least 97 mg/L, at least 97.5 mg/L, at least 98 mg/L, at least 98.5 mg/L, at least 99 mg/L, at least 99.5 mg/L, or at least 100 mg/L of a product (e.g., a compound of Formula (4), (5), and/or (6). In some instances, OLSs may form triketide (PDAL) and/or tetraketide (HTAL and olivetol) by-products. Triketides convert to PDAL, and tetraketides convert to HTAL and olivetol, not to olivetolic acid. In some embodiments, production of by-products is undesirable. In some embodiments, OLS enzymes described herein do not produce by-products or produce minimal by-products relative to a control. In some embodiments, OLS enzymes are selected, at least in part, based on the ratio of olivetolic acid produced relative to olivetol.

It was surprisingly discovered herein that OLSs can exhibit both OLS and OAC activity. PKS enzymes described in this application may or may not have cyclase activity. In some embodiments where the PKS enzyme does not have cyclase activity, one or more exogenous polynucleotides that encode a polyketide cyclase (PKC) enzyme may also be co-expressed in the same host cells to enable conversion of hexanoic acid or butyric acid or other fatty acid conversion into olivetolic acid or divarinolic acid or other precursors of cannabinoids. In some embodiments, the PKS enzyme and a PKC enzyme are expressed as separate and distinct enzymes. In some embodiments, a PKS enzyme that lacks cyclase activity and a PKC are linked as part of a fusion polypeptide that is a bifunctional PKS. In some embodiments, a bifunctional PKC is referred to as a bifunctional PKS-PKC. In some embodiments, a bifunctional PKC is a bifunctional tetraketide synthase (TKS-TKC).

As used in this application, a bifunctional PKS is an enzyme that is capable of producing a compound of Formula (6):

from a compound of Formula (2):

and a compound of Formula (3):

In some embodiments, a PKS produces more of a compound of Formula (6):

as compared to a compound of Formula (5):

As a non-limiting example, a compound of Formula (6):

is olivetolic acid (Formula (6a)):

As a non-limiting example, a compound of Formula (5):

is olivetol (Formula (5a)):

In some embodiments, a polyketide synthase of the present disclosure is capable of catalyzing a compound of Formula (2):

and a compound of Formula (3):

to produce a compound of Formula (4):

and also further catalyzes a compound of Formula (4):

to produce a compound of Formula (6):

In some embodiments, the PKS is not a fusion protein. In some embodiments, a PKS that is capable of catalyzing a compound of Formula (2):

and a compound of Formula (3):

to produce a compound of Formula (4):

and is also capable of further catalyzing the production of a compound of Formula (6):

from the compound of Formula (4):

is preferred because it avoids the need for an additional polyketide cyclase to produce a compound of Formula (6):

In some embodiments, such an enzyme that is a bifunctional PKS eliminates the transport considerations needed with addition of a polyketide cyclase, whereby the compound of Formula (4), being the product of the PKS, must be transported to the PKS for use as a substrate to be converted into the compound of Formula (6).

In some embodiments, a PKS is capable of producing olivetolic acid in the presence of a compound of Formula (2a):

and Formula (3a):

In some embodiments, an OLS is capable of producing olivetolic acid in the presence of a compound of Formula (2a):

and Formula (3a):

Without being bound by a particular theory, the presence of the amino acid W at a residue in a PKS corresponding to position 339 of SEQ ID NO: 6 may render or enhance bifunctionality of a PKS. In some embodiments, a bifunctional PKS comprises the amino acid W at a residue corresponding to position 339 of SEQ ID NO: 6. In some embodiments, a bifunctional PKS does not comprise the amino acid S at a residue corresponding to position 339 of SEQ ID NO: 6. As a non-limiting example, a PKS may comprise the amino acid substitution S332W relative to SEQ ID NO: 5 (see, e.g., t606899, SEQ ID NO: 298). In some embodiments, a PKS may comprise the amino acid substitution S339W relative to SEQ ID NO: 7 (see, e.g., t607377, SEQ ID NO: 409) In some embodiments, the PKS comprises a sequence that is at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or is 100% identical, including all values in between, to a sequence (e.g., nucleic acid or amino acid sequence) set forth in SEQ ID NO: 6.

In some embodiments, an OLS is capable of producing olivetolic acid in the presence of a compound of Formula (2a) and Formula (3a). In some embodiments, the OLS produces more olivetolic acid (OA) than olivetol. In some embodiments, the OLS produces at least 1.1 times, 1.2 times, 1.3 times, 1.4 times, 1.5 times, 1.6 times, 1.7 times, 1.8 times, 1.9 times, 2 times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, 2.7 times, 2.8 times, 2.9 times, 3 times, 3.1 times, 3.2 times, 3.3 times, 3.4 times, 3.5 times, 3.6 times, 3.7 times, 3.8 times, 3.9 times, 4 times, 5 times, 6 times, 8 times, 9 times, 10 times, 20 times, 30 times, 40 times, 50 times, 60 times, 70 times, 80 times, 90 times, 100 times, 200 times, 300 times, 400 times, 500 times, 600 times, 700 times, 800 times or 1,000 times more olivetolic acid (OA) than olivetol.

Without wishing to be bound by any theory, in some embodiments, bifunctional OLSs differ from other OLSs in the geometry of the substrate binding pocket, an internal substrate holding cavity, and/or a substrate exit tunnel. For example, the substrate binding pocket of the bifunctional OLSs may be wider as compared to the substrate binding pocket of Cannabis sativa OLS (SEQ ID NO: 5). Without wishing to be bound by any theory, this extra space may alleviate steric clashes between the protein and substrate and permit the pro-cyclization configuration.

Polyketide Cyclase (PKC)

A host cell described in this application may comprise a PKC. As used in this application, a “PKC” refers to an enzyme that is capable of cyclizing a polyketide.

In certain embodiments, a polyketide cyclase (PKC) catalyzes the cyclization of an oxo fatty acyl-CoA (e.g., a compound of Formula (4):

or 3,5,7-trioxododecanoyl-COA, 3,5,7-trioxodecanoyl-COA) to the corresponding intramolecular cyclization product (e.g., compound of Formula (6), including olivetolic acid and divarinic acid). In some embodiments, a PKC catalyzes the formation of a compound which occurs in the presence of a PKS. PKC substrates include trioxoalkanol-CoA, such as 3,5,7-Trioxododecanoyl-CoA, or a compound of Formula (4):

wherein R is hydrogen, optionally substituted acyl, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, or optionally substituted aryl. In certain embodiments, a PKC catalyzes a compound of Formula (4):

wherein R is hydrogen, optionally substituted acyl, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, or optionally substituted aryl; to form a compound of Formula (6):

wherein R is hydrogen, optionally substituted acyl, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, or optionally substituted aryl; as substrates. R is as defined in this application. In some embodiments, R is a C2-C6 optionally substituted alkyl. In some embodiments, R is a propyl or pentyl. In some embodiments, R is pentyl. In some embodiments, R is propyl. In certain embodiments, a PKC is an olivetolic acid cyclase (OAC). In certain embodiments, a PKC is a divarinic acid cyclase (DAC).

As one of ordinary skill in the art would appreciate a PKC could be obtained from any source, including naturally occurring sources and synthetic sources (e.g., a non-natually occurring PKC). In some embodiments, a PKC is from Cannabis. Non-limiting examples of PKCs include those disclosed in U.S. Pat. Nos. 9,611,460; 10,059,971; and US Pub 2019/0169661, which are incorporated by reference in this application in their entireties.

In some embodiments, a PKC is an OAC. As used in this application, an “OAC” refers to an enzyme that is capable of catalyzing the formation of olivetolic acid (OA). In some embodiments, an OAC is an enzyme that is capable of using a substrate of Formula (4a) (3,5,7-trioxododecanoyl-CoA):

to form a compound of Formula (6a) (olivetolic acid):

Olivetolic acid cyclase from C. sativa (CsOAC) is a 101 amino acid enzyme that performs non-decaboxylative cyclization of the tetraketide product of olivetol synthase (FIG. 4 Structure 4a) via aldol condensation to form olivetolic acid (FIG. 4 Structure 6a). CsOAC was identified and characterized by Gagne et al. (PNAS 2012) via transcriptome mining, and its cyclization function was recapitulated in vitro to demonstrate that CsOAC is required for formation of olivetolic acid in C. sativa. A crystal structure of the enzyme was published by Yang et al. (FEBS J. 2016 March; 283(6):1088-106), which revealed that the enzyme is a homodimer and belongs to the α+β barrel (DABB) superfamily of protein folds. CsOAC is the only known plant polyketide cyclase. Multiple fungal Type III polyketide synthases have been identified that perform both polyketide synthase and cyclization functions (Funa et al., J Biol Chem. 2007 May 11; 282(19):14476-81); however, in plants such a dual function enzyme has not yet been discovered.

A non-limiting example of an amino acid sequence encoding OAC in C. sativa is provided by UniProtKB—I6WU39 (SEQ ID NO: 125), which catalyzes the formation of olivetolic acid (OA) from 3,5,7-Trioxododecanoyl-CoA.

Prenyltransferase (PT)

A host cell described in this application may comprise a prenyltransferase (PT). As used in this application, a “PT” refers to an enzyme that is capable of transferring prenyl groups to acceptor molecule substrates. Non-limiting examples of prenyltransferases are described in WO2018200888 (e.g., CsPT4), U.S. Pat. No. 8,884,100 (e.g., CsPT1); CA2718469; Valliere et al., Nat Commun. 2019 Feb. 4; 10(1):565; and Luo et al., Nature 2019 Mar.; 567(7746):123-126, which are incorporated by reference in their entireties. In some embodiments, a PT is capable of producing cannabigerolic acid (CBGA), cannabigerovarinic acid (CBGVA), or other cannabinoids or cannabinoid-like substances. In some embodiments, a PT is cannabigerolic acid synthase (CBGAS). In some embodiments, a PT is cannabigerovarinic acid synthase (CBGVAS).

In some embodiments, the PT is an NphB prenyltransferase. See, e.g., U.S. Pat. No. 7,544,498; and Kumano et al., Bioorg Med Chem. 2008 Sep. 1; 16(17): 8117-8126, which are incorporated by reference in this application in their entireties. In some embodiments, a PT corresponds to NphB from Streptomyces sp. (see, e.g., UniprotKB Accession No. Q4R2T2; see also SEQ ID NO: 2 of U.S. Pat. No. 7,361,483). The protein sequence corresponding to UniprotKB Accession No. Q4R2T2 is provided by SEQ ID NO: 131:

Functional expression of paralog C. sativa CBGAS enzymes in S. cerevisiae and production of the major cannabinoid CBGA has been reported (Page and Boubakir US 20120144523, 2012, and Luo et al. Nature, 2019). Luo et al. reported the production of CBGA in S. cerevisiae by expressing a truncated version of a C. sativa CBGAS, CsPT4, with its native signal peptide removed (Luo et al. Nature, 2019). Without being bound by a particular theory, the integral-membrane nature of C. sativa CBGAS enzymes may render functional expression of C. sativa CBGAS enzymes in heterologous hosts challenging. Removal of transmembrane domain(s) or signal sequences or use of prenyltransferases that are not associated with the membrane and are not integral membrane proteins may facilitate increased interaction between the enzyme and available substrate, for example in the cellular cytosol and/or in organelles that may be targeted using peptides that confer localization.

In some embodiments, the PT is a soluble PT. In some embodiments, the PT is a cytosolic PT. In some embodiments, the PT is a secreted protein. In some embodiments, the PT is not a membrane-associated protein. In some embodiments, the PT is not an integral membrane protein. In some embodiments, the PT does not comprise a transmembrane domain or a predicted transmembrane. In some embodiments, the PT may be primarily detected in the cytosol (e.g., detected in the cytosol to a greater extent than detected associated with the cell membrane). In some embodiments, the PT is a protein from which one or more transmembrane domains have been removed and/or mutated (e.g., by truncation, deletions, substitutions, insertions, and/or additions) so that the PT localizes or is predicted to localize in the cytosol of the host cell, or to cytosolic organelles within the host cell, or, in the case of bacterial hosts, in the periplasm. In some embodiments, the PT is a protein from which one or more transmembrane domains have been removed or mutated (e.g., by truncation, deletions, substitutions, insertions, and/or additions) so that the PT has increased localization to the cytosol, organelles, or periplasm of the host cell, as compared to membrane localization.

Within the scope of the term “transmembrane domains” are predicted or putative transmembrane domains in addition to transmembrane domains that have been empirically determined. In general, transmembrane domains are characterized by a region of hydrophobicity that facilitates integration into the cell membrane. Methods of predicting whether a protein is a membrane protein or a membrane-associated protein are known in the art and may include, for example, amino acid sequence analysis, hydropathy plots, and/or protein localization assays.

In some embodiments, the PT is a protein from which a signal sequence has been removed and/or mutated so that the PT is not directed to the cellular secretory pathway. In some embodiments, the PT is a protein from which a signal sequence has been removed and/or mutated so that the PT is localized to the cytosol or has increased localization to the cytosol (e.g., as compared to the secretory pathway).

In some embodiments, the PT is a secreted protein. In some embodiments, the PT contains a signal sequence.

In some embodiments, a PT is a fusion protein. For example, a PT may be fused to one or more genes in the metabolic pathway of a host cell. In certain embodiments, a PT may be fused to mutant forms of one or more genes in the metabolic pathway of a host cell.

In some embodiments, a PT described in this application transfers one or more prenyl groups to any of positions 1, 2, 3, 4, or 5 in a compound of Formula (6), shown below:

In some embodiments, the PT transfers a prenyl group to any of positions 1, 2, 3, 4, or 5 in a compound of Formula (6), shown below:

to form a compound of one or more of Formula (8w), Formula (8x), Formula (8′), Formula (8y), Formula (8z):

or a pharmaceutically acceptable salt, solvate, hydrate, polymorph, co-crystal, tautomer, stereoisomer, isotopically labeled derivative, or prodrug thereof, wherein a is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10.

Terminal Synthases (TS)

A host cell described in this application may comprise a terminal synthase (TS). As used in this application, a “TS” refers to an enzyme that is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) to produce a ring-containing product (e.g., heterocyclic ring-containing product). In certain embodiments, a TS is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) to produce a carbocyclic-ring containing product (e.g., cannabinoid). In certain embodiments, a TS is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) to produce a heterocyclic-ring containing product (e.g., cannabinoid). In certain embodiments, a TS is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) to produce a cannabinoid.

In some embodiments, a TS is a tetrahydrocannabinolic acid synthase (THCAS), a cannabidiolic acid synthase (CBDAS), and/or a cannabichromenic acid synthase (CBCAS). As one of ordinary skill in the art would appreciate a TS could be obtained from any source, including naturally occurring sources and synthetic sources (e.g., a non-natually occurring TS).

a. Substrates

A TS may be capable of using one or more substrates. In some instances, the location of the prenyl group and/or the R group differs between TS substrates. For example, a TS may be capable of using as a substrate one or more compounds of Formula (8w), Formula (8x), Formula (8′), Formula (8y), and/or Formula (8z):

or a pharmaceutically acceptable salt, solvate, hydrate, polymorph, co-crystal, tautomer, stereoisomer, isotopically labeled derivative, or prodrug thereof, wherein a is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10.

In certain embodiments, a compound of Formula (8′) is a compound of Formula (8):

In some embodiments, a TS catalyzes oxidative cyclization of the prenyl moiety (e.g., terpene) of a compound of Formula (8) described in this application and shown in FIG. 2. In certain embodiments, a compound of Formula (8) is a compound of Formula (8a):

b. Products

In embodiments wherein CBGA is the substrate, the TS enzymes CBDAS, THCAS and CBCAS would generally catalyze the formation of cannabidiolic acid (CBDA), A9-tetrahydrocannabinolic acid (THCA) and cannabichromenic acid (CBCA), respectively. However, in some embodiments, a TS can produce more than one different product depending on reaction conditions. For example, the pH of the reaction environment may cause a THCAS or a CBDAS to produce CBCA in greater proportions than THCA or CBDAS, respectively (see, for example, U.S. Pat. No. 9,359,625 to Winnicki and Donsky, incorporated by reference in its entirety).

A TS may be capable of using one or more substrates described in this application to produce one or more products. Non-limiting example of TS products are shown in Table 1. In some instances, a TS is capable of using one substrate to produce 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 different products. In some embodiments, a TS is capable of using more than one substrate to produce 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 different products.

In some embodiments, a TS is capable of producing a compound of Formula (X-A) and/or a compound of Formula (X-B):

Tetrahydrocannabinolic Acid Synthase (THCAS)

A host cell described in this application may comprise a TS that is a tetrahydrocannabinolic acid synthase (THCAS). As used in this application “tetrahydrocannabinolic acid synthase (THCAS)” or “Δ¹-tetrahydrocannabinolic acid (THCA) synthase” refers to an enzyme that is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) of a compound of Formula (8) to produce a ring-containing product (e.g., heterocyclic ring-containing product, carbocyclic-ring containing product) of Formula (10). In certain embodiments, a THCAS refers to an enzyme that is capable of producing Δ9-tetrahydrocannabinolic acid (A9-THCA, THCA, A9-Tetrahydro-cannabivarinic acid A (A9-THCVA-C3 A), THCVA, THCP, or a compound of Formula 10(a), from a compound of Formula (8). In certain embodiments, a THCAS is capable of producing Δ⁹-tetrahydrocannabinolic acid (Δ⁹-THCA, THCA, or a compound of Formula 10(a)).

A THCAS may use cannabigerolic acid (CBGA) as a substrate. In some embodiments, the THCAS produces Δ⁹-THCA from CBGA. In some embodiments, a THCAS may catalyze the oxidative cyclization of other substrates, such as 3-geranyl-2,4-dihydro-6-alkylbenzoic acids. In some embodiments, a THCAS may catalyze the oxidative cyclization of other substrates, such as 3-geranyl-2,4-dihydro-6-alkylbenzoic acids like cannabigerovarinic acid (CBGVA)). In some embodiments, a THCAS exhibits specificity for CBGA substrates. In some embodiments, a THCAS may use cannabivarinic acid (CBDVA) as a substrate. In some embodiments, the THCAS exhibits specificity for CBDVA substrates. In some embodiments, a THCAS may use cannabiphorol acid (CBDP) as a substrate. In some embodiments, the THCAS exhibits specificity for CBDP substrates.

In some embodiments, a THCAS is from C. sativa. C. sativa THCAS performs the oxidative cyclization of the geranyl moiety of Cannabigerolic Acid (CBGA) (FIG. 4 Structure 8a) to form Tetrahydrocannabinolic Acid (FIG. 4 Structure 10a) using covalently bound flavin adenine dinucleotide (FAD) as a cofactor and molecular oxygen as the final electron acceptor. THCAS was first discovered and characterized by Taura et al. (JACS. 1995) following extraction of the enzyme from the leaf buds of C. sativa and confirmation of its THCA synthase activity in vitro upon the addition of CBGA as a substrate. Additional analysis indicated that the enzyme is a monomer and possesses FAD binding and Berberine Bridge Enzyme (BBE) sequence motifs. A crystal structure of the enzyme published by Shoyama et al. (J Mol Biol. 2012 Oct. 12; 423(1):96-105) revealed that the enzyme covalently binds to a molecule of the cofactor FAD. See also, e.g., Sirikantarams et al., J. Biol. Chem. 2004 Sep. 17; 279(38):39767-39774. There are several THCAS isozymes in Cannabis sativa.

In some embodiments, a C. sativa THCAS (Uniprot KB Accession No.: I1V0C5) comprises the amino acid sequence shown below:

Cannabidiolic Acid Synthase (CBDAS)

A host cell described in this application may comprise a TS that is a cannabidiolic acid synthase (CBDAS). As used in this application, a “CBDAS” refers to an enzyme that is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) of a compound of Formula (8) to produce a compound of Formula 9. In some embodiments, a compound of Formula 9 is a compound of Formula (9a) (cannabidiolic acid (CBDA)), CBDVA, or CBDP. A CBDAS may use cannabigerolic acid (CBGA) or cannabinerolic acid as a substrate. In some embodiments, a cannabidiolic acid synthase is capable of oxidative cyclization of cannabigerolic acid (CBGA) to produce cannabidiolic acid (CBDA). In some embodiments, the CBDAS may catalyze the oxidative cyclization of other substrates, such as 3-geranyl-2,4-dihydro-6-alkylbenzoic acids like cannabigerovarinic acid (CBVGA).

Cannabichromenic Acid Synthase (CBCAS)

A host cell described in this application may comprise a TS that is a cannabichromenic acid synthase (CBCAS). As used in this application, a “CBCAS” refers to an enzyme that is capable of catalyzing oxidative cyclization of a prenyl moiety (e.g., terpene) of a compound of Formula (8) to produce a compound of Formula (11). In some embodiments, a compound of Formula (11) is a compound of Formula (11a) (cannabichromenic acid (CBCA)), CBCVA, or CBCPA. A CBCAS may use cannabigerolic acid (CBGA) as a substrate. In some embodiments, a CBCAS produces cannabichromenic acid (CBCA) from cannabigerolic acid (CBGA). In some embodiments, the CBCAS may catalyze the oxidative cyclization of other substrates, such as 3-geranyl-2,4-dihydro-6-alkylbenzoic acids like cannabigerovarinic acid (CBVGA), or CBCPA. In some embodiments, the CBCAS exhibits specificity for CBGA substrates.

In some embodiments, a CBCAS is from Cannabis. In C. sativa, an amino acid sequence encoding CBCAS is provided by, and incorporated by reference from, SEQ ID NO:2 disclosed in U.S. Patent Publication No. 20170211049. In other embodiments, a CBCAS may be a THCAS described in and incorporated by reference from U.S. Pat. No. 9,359,625. SEQ ID NO:2 disclosed in U.S. Patent Publication No. 20170211049 (corresponding to SEQ ID NO: 113 in this application) has the amino acid sequence:

Any of the enzymes, host cells, and methods described in this application may be used for the production of cannabinoids and cannabinoid precursors, such as those provided in Table 1. In general, the term “production” is used to refer to the generation of one or more products (e.g., products of interest and/or by-products/off-products), for example, from a particular substrate or reactant. The amount of production may be evaluated at any one or more steps of a pathway, such as a final product or an intermediate product, using metrics familiar to one of ordinary skill in the art. For example, the amount of production may be assessed for a single enzymatic reaction (e.g., conversion of a compound of Formula (8) to a compound of Formula (10) by a TS). Alternatively or in addition, the amount of production may be assessed for a series of enzymatic reactions (e.g., the biosynthetic pathway shown in FIG. 1 and/or FIG. 2). Production may be assessed by any metrics known in the art, for example, by assessing volumetric productivity, enzyme kinetics/reaction rate, specific productivity biomass-specific productivity, titer, yield, and total titer of one or more products (e.g., products of interest and/or by-products/off-products).

In some embodiments, the metric used to measure production may depend on whether a continuous process is being monitored (e.g., several cannabinoid biosynthesis steps are used in combination) or whether a particular end product is being measured. For example, in some embodiments, metrics used to monitor production by a continuous process may include volumetric productivity, enzyme kinetics and reaction rate. In some embodiments, metrics used to monitor production of a particular product may include specific productivity, biomass-specific productivity, titer, yield, and/or total titer of one or more products (e.g., products of interest and/or by-products/off-products).

Production of one or more products (e.g., products of interest and/or by-products/off-products) may be assessed indirectly, for example by determining the amount of a substrate remaining following termination of the reaction/fermentation. For example, for a TS that catalyzes the formation of products (e.g., a compound of Formula (10), including tetrahydrocannabinolic acid (THCA) (Formula (10a)) from a compound of Formula (8), including CBGA (Formula 8(a))), production of the products may be assessed by quantifying the compound of Formula (10) directly or by quantifying the amount of substrate remaining following the reaction (e.g., amount of the compound of Formula (8)).

Variants

Aspects of the disclosure relate to nucleic acids encoding any of the polypeptides (e.g., AAE, PKS, PKC, PT, or TS) described in this application. In some embodiments, a nucleic acid encompassed by the disclosure is a nucleic acid that hybridizes under high or medium stringency conditions to a nucleic acid encoding an AAE, PKS, PKC, PT, or TS and is biologically active. For example, high stringency conditions of 0.2 to 1×SSC at 65° C. followed by a wash at 0.2×SSC at 65° C. can be used. In some embodiments, a nucleic acid encompassed by the disclosure is a nucleic acid that hybridizes under low stringency conditions to a nucleic acid encoding an AAE, PKS, PKC, PT, or TS and is biologically active. For example, low stringency conditions of 6×SSC at room temperature followed by a wash at 2×SSC at room temperature can be used. Other hybridization conditions include 3×SSC at 40 or 50° C., followed by a wash in 1 or 2×SSC at 20, 30, 40, 50, 60, or 65° C.

Hybridizations can be conducted in the presence of formaldehyde, e.g., 10%, 20%, 30% 40% or 50%, which further increases the stringency of hybridization. Theory and practice of nucleic acid hybridization is described, e.g., in S. Agrawal (ed.) Methods in Molecular Biology, volume 20; and Tijssen (1993) Laboratory Techniques in biochemistry and molecular biology-hybridization with nucleic acid probes, e.g., part I chapter 2 “Overview of principles of hybridization and the strategy of nucleic acid probe assays,” Elsevier, New York provide a basic guide to nucleic acid hybridization.

Variants of enzyme sequences described in this application (e.g., AAE, PKS, PKC, PT, or TS, including nucleic acid or amino acid sequences) are also encompassed by the present disclosure. A variant may share at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% sequence identity with a reference sequence, including all values in between.

Unless otherwise noted, the term “sequence identity,” as known in the art, refers to a relationship between the sequences of two polypeptides or polynucleotides, as determined by sequence comparison (alignment). In some embodiments, sequence identity is determined across the entire length of a sequence (e.g., AAE, PKS, PKC, PT, or TS sequence). In some embodiments, sequence identity is determined over a region (e.g., a stretch of amino acids or nucleic acids, e.g., the sequence spanning an active site) of a sequence (e.g., AAE, PKS, PKC, PT, or TS sequence).

Identity can also refer to the degree of sequence relatedness between two sequences as determined by the number of matches between strings of two or more residues (e.g., nucleic acid or amino acid residues). Identity measures the percent of identical matches between the smaller of two or more sequences with gap alignments (if any) addressed by a particular mathematical model, algorithms, or computer program.

Identity of related polypeptides or nucleic acid sequences can be readily calculated by any of the methods known to one of ordinary skill in the art. The “percent identity” of two sequences (e.g., nucleic acid or amino acid sequences) may, for example, be determined using the algorithm of Karlin and Altschul Proc. Natl. Acad. Sci. USA 87:2264-68, 1990, modified as in Karlin and Altschul Proc. Natl. Acad. Sci. USA 90:5873-77, 1993. Such an algorithm is incorporated into the NBLAST® and XBLAST® programs (version 2.0) of Altschul et al., J. Mol. Biol. 215:403-10, 1990. BLAST® protein searches can be performed, for example, with the XBLAST program, score=50, wordlength=3 to obtain amino acid sequences homologous to the proteins described in this application. Where gaps exist between two sequences, Gapped BLAST® can be utilized, for example, as described in Altschul et al., Nucleic Acids Res. 25(17):3389-3402, 1997. When utilizing BLAST® and Gapped BLAST® programs, the default parameters of the respective programs (e.g., XBLAST® and NBLAST®) can be used, or the parameters can be adjusted appropriately as would be understood by one of ordinary skill in the art.

Another local alignment technique which may be used, for example, is based on the Smith-Waterman algorithm (Smith, T. F. & Waterman, M. S. (1981) “Identification of common molecular subsequences.” J. Mol. Biol. 147:195-197). A general global alignment technique which may be used, for example, is the Needleman-Wunsch algorithm (Needleman, S. B. & Wunsch, C. D. (1970) “A general method applicable to the search for similarities in the amino acid sequences of two proteins.” J. Mol. Biol. 48:443-453), which is based on dynamic programming.

More recently, a Fast Optimal Global Sequence Alignment Algorithm (FOGSAA) was developed that purportedly produces global alignment of nucleic acid and amino acid sequences faster than other optimal global alignment methods, including the Needleman-Wunsch algorithm. In some embodiments, the identity of two polypeptides is determined by aligning the two amino acid sequences, calculating the number of identical amino acids, and dividing by the length of one of the amino acid sequences. In some embodiments, the identity of two nucleic acids is determined by aligning the two nucleotide sequences and calculating the number of identical nucleotide and dividing by the length of one of the nucleic acids.

For multiple sequence alignments, computer programs including Clustal Omega (Sievers et al., Mol Syst Biol. 2011 Oct. 11; 7:539) may be used.

It should be appreciated that a sequence, including a nucleic acid or amino acid sequence, may be found to have a specified percent identity to a reference sequence, such as a sequence disclosed in this application and/or recited in the claims, using any method known to one of ordinary skill in the art. Different algorithms may yield different percent identity values for a given set of sequences. The claims of this application should be understood to encompass sequences for which percent identity to a reference sequence is calculated using default parameters and/or parameters typically used by the skilled artisan for a given algorithm.

In some embodiments, a sequence, including a nucleic acid or amino acid sequence, is found to have a specified percent identity to a reference sequence, such as a sequence disclosed in this application and/or recited in the claims when sequence identity is determined using the algorithm of Karlin and Altschul Proc. Nat. Acad. Sci. USA 87:2264-68, 1990, modified as in Karlin and Altschul Proc. Nat. Acad. Sci. USA 90:5873-77, 1993 (e.g., BLAST®, NBLAST®, XBLAST® or Gapped BLAST® programs, using default parameters of the respective programs).

In some embodiments, a sequence, including a nucleic acid or amino acid sequence, is found to have a specified percent identity to a reference sequence, such as a sequence disclosed in this application and/or recited in the claims when sequence identity is determined using the Smith-Waterman algorithm (Smith, T. F. & Waterman, M. S. (1981) “Identification of common molecular subsequences.” J. Mol. Biol. 147:195-197) or the Needleman-Wunsch algorithm (Needleman, S. B. & Wunsch, C. D. (1970) “A general method applicable to the search for similarities in the amino acid sequences of two proteins.” J. Mol. Biol. 48:443-453).

In some embodiments, a sequence, including a nucleic acid or amino acid sequence, is found to have a specified percent identity to a reference sequence, such as a sequence disclosed in this application and/or recited in the claims when sequence identity is determined using a Fast Optimal Global Sequence Alignment Algorithm (FOGSAA).

In some embodiments, a sequence, including a nucleic acid or amino acid sequence, is found to have a specified percent identity to a reference sequence, such as a sequence disclosed in this application and/or recited in the claims when sequence identity is determined using Clustal Omega (Sievers et al., Mol Syst Biol. 2011 Oct. 11; 7:539).

As used in this application, a residue (such as a nucleic acid residue or an amino acid residue) in sequence “X” is referred to as corresponding to a position or residue (such as a nucleic acid residue or an amino acid residue) “Z” in a different sequence “Y” when the residue in sequence “X” is at the counterpart position of “Z” in sequence “Y” when sequences X and Y are aligned using amino acid sequence alignment tools known in the art.

As used in this application, variant sequences may be homologous sequences. As used in this application, homologous sequences are sequences (e.g., nucleic acid or amino acid sequences) that share a certain percent identity (e.g., at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% percent identity, including all values in between). Homologous sequences include but are not limited to paralogous or orthologous sequences. Paralogous sequences arise from duplication of a gene within a genome of a species, while orthologous sequences diverge after a speciation event.

In some embodiments, a polypeptide variant (e.g., AAE, PKS, PKC, PT, or TS enzyme variant) comprises a domain that shares a secondary structure (e.g., alpha helix, beta sheet) with a reference polypeptide (e.g., a reference AAE, PKS, PKC, PT, or TS enzyme). In some embodiments, a polypeptide variant (e.g., AAE, PKS, PKC, PT, or TS enzyme variant) shares a tertiary structure with a reference polypeptide (e.g., a reference AAE, PKS, PKC, PT, or TS enzyme). As a non-limiting example, a polypeptide variant (e.g., AAE, PKS, PKC, PT, or TS enzyme) may have low primary sequence identity (e.g., less than 80%, less than 75%, less than 70%, less than 65%, less than 60%, less than 55%, less than 50%, less than 45%, less than 40%, less than 35%, less than 30%, less than 25%, less than 20%, less than 15%, less than 10%, or less than 5% sequence identity) compared to a reference polypeptide, but share one or more secondary structures (e.g., including but not limited to loops, alpha helices, or beta sheets), or have the same tertiary structure as a reference polypeptide. For example, a loop may be located between a beta sheet and an alpha helix, between two alpha helices, or between two beta sheets. Homology modeling may be used to compare two or more tertiary structures.

Functional variants of the recombinant AAE, PKS, PKC, PT, or TS enzyme disclosed in this application are encompassed by the present disclosure. For example, functional variants may bind one or more of the same substrates or produce one or more of the same products. Functional variants may be identified using any method known in the art. For example, the algorithm of Karlin and Altschul Proc. Natl. Acad. Sci. USA 87:2264-68, 1990 described above may be used to identify homologous proteins with known functions.

Putative functional variants may also be identified by searching for polypeptides with functionally annotated domains. Databases including Pfam (Sonnhammer et al., Proteins. 1997 July; 28(3):405-20) may be used to identify polypeptides with a particular domain.

Homology modeling may also be used to identify amino acid residues that are amenable to mutation (e.g., substitution, deletion, and/or insertion) without affecting function. A non-limiting example of such a method may include use of position-specific scoring matrix (PSSM) and an energy minimization protocol.

Position-specific scoring matrix (PSSM) uses a position weight matrix to identify consensus sequences (e.g., motifs). PSSM can be conducted on nucleic acid or amino acid sequences. Sequences are aligned and the method takes into account the observed frequency of a particular residue (e.g., an amino acid or a nucleotide) at a particular position and the number of sequences analyzed. See, e.g., Stormo et al., Nucleic Acids Res. 1982 May 11; 10(9):2997-3011. The likelihood of observing a particular residue at a given position can be calculated. Without being bound by a particular theory, positions in sequences with high variability may be amenable to mutation (e.g., substitution, deletion, and/or insertion; e.g., PSSM score >0) to produce functional homologs.

PSSM may be paired with calculation of a Rosetta energy function, which determines the difference between the wild-type and the single-point mutant. The Rosetta energy function calculates this difference as (ΔΔ_(calc)). With the Rosetta function, the bonding interactions between a mutated residue and the surrounding atoms are used to determine whether an amino acid substitution, deletion, or insertion increases or decreases protein stability. For example, an amino acid substitution, deletion, or insertion that is designated as favorable by the PSSM score (e.g. PSSM score 0), can then be analyzed using the Rosetta energy function to determine the potential impact of the amino acid substitution, deletion, or insertion on protein stability. Without being bound by a particular theory, potentially stabilizing amino acid substitutions, deletions, or insertions are desirable for protein engineering (e.g., production of functional homologs). In some embodiments, a potentially stabilizing amino acid substitution, deletion, or insertion has a ΔΔG_(calc), value of less than −0.1 (e.g., less than −0.2, less than −0.3, less than −0.35, less than −0.4, less than −0.45, less than −0.5, less than −0.55, less than −0.6, less than −0.65, less than −0.7, less than −0.75, less than −0.8, less than −0.85, less than −0.9, less than −0.95, or less than −1.0) Rosetta energy units (R.e.u.). See, e.g., Goldenzweig et al., Mol Cell. 2016 Jul. 21; 63(2):337-346. Doi: 10.1016/j.molcel.2016.06.012.

In some embodiments, an AAE, PKS, PKC, PT, or TS enzyme coding sequence comprises an amino acid substitution, deletion, and/or insertion at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 or more than 100 positions corresponding to a reference (e.g., AAE, PKS, PKC, PT, or TS enzyme) coding sequence. In some embodiments, the AAE, PKS, PKC, PT, or TS enzyme coding sequence comprises an amino acid substitution, deletion, and/or insertion in 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 or more codons of the coding sequence relative to a reference (e.g., AAE, PKS, PKC, PT, or TS enzyme) coding sequence. As will be understood by one of ordinary skill in the art, a substitution, insertion, or deletion within a codon may or may not change the amino acid that is encoded by the codon due to degeneracy of the genetic code. In some embodiments, the one or more substitutions, insertions, or deletions in the coding sequence do not alter the amino acid sequence of the coding sequence (e.g., AAE, PKS, PKC, PT, or TS enzyme) relative to the amino acid sequence of a reference polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme).

In some embodiments, the one or more substitutions, deletions, and/or insertions in a recombinant AAE, PKS, PKC, PT, or TS enzyme sequence alters the amino acid sequence of the polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme) relative to the amino acid sequence of a reference polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme). In some embodiments, the one or more substitutions, insertions, or deletions alters the amino acid sequence of the recombinant polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme) relative to the amino acid sequence of a reference polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme) and alters (enhances or reduces) an activity of the polypeptide relative to the reference polypeptide.

The activity (e.g., specific activity) of any of the recombinant polypeptides described in this application (e.g., AAE, PKS, PKC, PT, or TS enzyme) may be measured using routine methods. As a non-limiting example, a recombinant polypeptide's activity may be determined by measuring its substrate specificity, product(s) produced, the concentration of product(s) produced, or any combination thereof. As used in this application, “specific activity” of a recombinant polypeptide refers to the amount (e.g., concentration) of a particular product produced for a given amount (e.g., concentration) of the recombinant polypeptide per unit time.

The skilled artisan will also realize that insertions, substitutions, or deletions in a recombinant polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme) coding sequence may result in conservative amino acid substitutions to provide functionally equivalent variants of the foregoing polypeptides, e.g., variants that retain the activities of the polypeptides. As used in this application, a “conservative amino acid substitution” refers to an amino acid substitution that does not alter the relative charge or size characteristics or functional activity of the protein in which the amino acid substitution is made.

In some instances, an amino acid is characterized by its R group (see, e.g., Table 3). For example, an amino acid may comprise a nonpolar aliphatic R group, a positively charged R group, a negatively charged R group, a nonpolar aromatic R group, or a polar uncharged R group. Non-limiting examples of an amino acid comprising a nonpolar aliphatic R group include alanine, glycine, valine, leucine, methionine, and isoleucine. Non-limiting examples of an amino acid comprising a positively charged R group includes lysine, arginine, and histidine. Non-limiting examples of an amino acid comprising a negatively charged R group include aspartate and glutamate. Non-limiting examples of an amino acid comprising a nonpolar, aromatic R group include phenylalanine, tyrosine, and tryptophan. Non-limiting examples of an amino acid comprising a polar uncharged R group include serine, threonine, cysteine, proline, asparagine, and glutamine.

Non-limiting examples of functionally equivalent variants of polypeptides may include conservative amino acid substitutions in the amino acid sequences of proteins disclosed in this application. As used in this application “conservative substitution” is used interchangeably with “conservative amino acid substitution” and refers to any one of the amino acid substitutions provided in Table 2.

In some embodiments, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more than 20 residues can be changed when preparing variant polypeptides. In some embodiments, amino acids are replaced by conservative amino acid substitutions.

Amino acid substitutions in the amino acid sequence of a polypeptide to produce a recombinant polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme) variant having a desired property and/or activity can be made by alteration of the coding sequence of the polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme). Similarly, conservative amino acid substitutions in the amino acid sequence of a polypeptide to produce functionally equivalent variants of the polypeptide typically are made by alteration of the coding sequence of the recombinant polypeptide (e.g., AAE, PKS, PKC, PT, or TS enzyme).

Mutations (e.g., substitutions, insertions, additions, or deletions) can be made in a nucleic acid sequence by a variety of methods known to one of ordinary skill in the art. For example, mutations (e.g., substitutions, insertions, additions, or deletions) can be made by PCR-directed mutation, site-directed mutagenesis according to the method of Kunkel (Kunkel, Proc. Nat. Acad. Sci. U.S.A. 82: 488-492, 1985), by chemical synthesis of a gene encoding a polypeptide, by CRISPR, or by insertions, such as insertion of a tag (e.g., a HIS tag or a GFP tag). Mutations can include, for example, substitutions, insertions, additions, deletions, and translocations, generated by any method known in the art. Methods for producing mutations may be found in in references such as Molecular Cloning: A Laboratory Manual, J. Sambrook, et al., eds., Fourth Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 2012, or Current Protocols in Molecular Biology, F. M. Ausubel, et al., eds., John Wiley & Sons, Inc., New York, 2010.

In some embodiments, methods for producing variants include circular permutation (Yu and Lutz, Trends Biotechnol. 2011 January; 29(1):18-25). In circular permutation, the linear primary sequence of a polypeptide can be circularized (e.g., by joining the N-terminal and C-terminal ends of the sequence) and the polypeptide can be severed (“broken”) at a different location. Thus, the linear primary sequence of the new polypeptide may have low sequence identity (e.g., less than 80%, less than 75%, less than 70%, less than 65%, less than 60%, less than 55%, less than 50%, less than 45%, less than 40%, less than 35%, less than 30%, less than 25%, less than 20%, less than 15%, less than 10%, less or less than 5%, including all values in between) as determined by linear sequence alignment methods (e.g., Clustal Omega or BLAST). Topological analysis of the two proteins, however, may reveal that the tertiary structure of the two polypeptides is similar or dissimilar. Without being bound by a particular theory, a variant polypeptide created through circular permutation of a reference polypeptide and with a similar tertiary structure as the reference polypeptide can share similar functional characteristics (e.g., enzymatic activity, enzyme kinetics, substrate specificity or product specificity). In some instances, circular permutation may alter the secondary structure, tertiary structure or quaternary structure and produce an enzyme with different functional characteristics (e.g., increased or decreased enzymatic activity, different substrate specificity, or different product specificity). See, e.g., Yu and Lutz, Trends Biotechnol. 2011 January; 29(1):18-25.

It should be appreciated that in a protein that has undergone circular permutation, the linear amino acid sequence of the protein would differ from a reference protein that has not undergone circular permutation. However, one of ordinary skill in the art would be able to determine which residues in the protein that has undergone circular permutation correspond to residues in the reference protein that has not undergone circular permutation by, for example, aligning the sequences and detecting conserved motifs, and/or by comparing the structures or predicted structures of the proteins, e.g., by homology modeling.

In some embodiments, an algorithm that determines the percent identity between a sequence of interest and a reference sequence described in this application accounts for the presence of circular permutation between the sequences. The presence of circular permutation may be detected using any method known in the art, including, for example, RASPODOM (Weiner et al., Bioinformatics. 2005 Apr. 1; 21(7):932-7). In some embodiments, the presence of circulation permutation is corrected for (e.g., the domains in at least one sequence are rearranged) prior to calculation of the percent identity between a sequence of interest and a sequence described in this application. The claims of this application should be understood to encompass sequences for which percent identity to a reference sequence is calculated after taking into account potential circular permutation of the sequence.

Aspects of the present disclosure relate to recombinant enzymes, functional modifications and variants thereof, as well as their uses. For example, the methods described in this application may be used to produce cannabinoids and/or cannabinoid precursors. The methods may comprise using a host cell comprising an enzyme disclosed in this application, cell lysate, isolated enzymes, or any combination thereof. Methods comprising recombinant expression of genes encoding an enzyme disclosed in this application in a host cell are encompassed by the present disclosure. In vitro methods comprising reacting one or more cannabinoid precursors or cannabinoids in a reaction mixture with an enzyme disclosed in this application are also encompassed by the present disclosure. In some embodiments, the enzyme is a TS.

A nucleic acid encoding any of the recombinant polypeptides (e.g., AAE, PKS, PKC, PT, or TS enzyme) described in this application may be incorporated into any appropriate vector through any method known in the art. For example, the vector may be an expression vector, including but not limited to a viral vector (e.g., a lentiviral, retroviral, adenoviral, or adeno-associated viral vector), any vector suitable for transient expression, any vector suitable for constitutive expression, or any vector suitable for inducible expression (e.g., a galactose-inducible or doxycycline-inducible vector).

A vector encoding any of the recombinant polypeptides (e.g., AAE, PKS, PKC, PT, or TS enzyme) described in this application may be introduced into a suitable host cell using any method known in the art. Non-limiting examples of yeast transformation protocols are described in Gietz et al., Yeast transformation can be conducted by the LiAc/SS Carrier DNA/PEG method. Methods Mol Biol. 2006; 313:107-20, which is hereby incorporated by reference in its entirety. Host cells may be cultured under any conditions suitable as would be understood by one of ordinary skill in the art. For example, any media, temperature, and incubation conditions known in the art may be used. For host cells carrying an inducible vector, cells may be cultured with an appropriate inducible agent to promote expression.

In some embodiments, a vector replicates autonomously in the cell. In some embodiments, a vector integrates into a chromosome within a cell. A vector can contain one or more endonuclease restriction sites that are cut by a restriction endonuclease to insert and ligate a nucleic acid containing a gene described in this application to produce a recombinant vector that is able to replicate in a cell. Vectors are typically composed of DNA, although RNA vectors are also available. Cloning vectors include, but are not limited to: plasmids, fosmids, phagemids, virus genomes and artificial chromosomes. As used in this application, the terms “expression vector” or “expression construct” refer to a nucleic acid construct, generated recombinantly or synthetically, with a series of specified nucleic acid elements that permit transcription of a particular nucleic acid in a host cell (e.g., microbe), such as a yeast cell. In some embodiments, the nucleic acid sequence of a gene described in this application is inserted into a cloning vector so that it is operably joined to regulatory sequences and, in some embodiments, expressed as an RNA transcript. In some embodiments, the vector contains one or more markers, such as a selectable marker as described in this application, to identify cells transformed or transfected with the recombinant vector. In some embodiments, a host cell has already been transformed with one or more vectors. In some embodiments, a host cell that has been transformed with one or more vectors is subsequently transformed with one or more vectors. In some embodiments, a host cell is transformed simultaneously with more than one vector. In some embodiments, the nucleic acid sequence of a gene described in this application is recoded. Recoding may increase production of the gene product by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100%, including all values in between) relative to a reference sequence that is not recoded.

In some embodiments, the nucleic acid encoding any of the proteins described in this application is under the control of regulatory sequences (e.g., enhancer sequences). In some embodiments, a nucleic acid is expressed under the control of a promoter. The promoter can be a native promoter, e.g., the promoter of the gene in its endogenous context, which provides normal regulation of expression of the gene. Alternatively, a promoter can be a promoter that is different from the native promoter of the gene, e.g., the promoter is different from the promoter of the gene in its endogenous context.

In some embodiments, the promoter is a eukaryotic promoter. Non-limiting examples of eukaryotic promoters include TDH3, PGK1, PKC1, PDC1, TEF1, TEF2, RPL18B, SSA1, TDH2, PYK1, TPI1, GAL1, GAL10, GAL7, GAL3, GAL2, MET3, MET25, HXT3, HXT7, ACT1, ADH1, ADH2, CUP1-1, ENO2, and SOD1, as would be known to one of ordinary skill in the art (see, e.g., Addgene website: blog.addgene.org/plasmids-101-the-promoter-region).

Non-limiting examples of bacterial promoters include Pbad, PmgrB, Ptrc2, Plac/ara, Ptac, and Pm.

In some embodiments, the promoter is an inducible promoter. As used in this application, an “inducible promoter” is a promoter controlled by the presence or absence of a molecule. This may be used, for example, to controllably induce the expression of an enzyme. In some embodiments, an inducible promoter linked to a PT and/or a TS may be used to regulate expression of the enzyme(s), for example to reduce cannabinoid production in certain scenarios (e.g., during transport of the genetically modified organism to satisfy regulatory restrictions in certain jurisdictions, or between jurisdictions where cannabinoids may not be shipped). In some embodiments, an inducible promoter linked to a CBGAS and/or a TS, the CBGAS and/or TS may be used to regulate expression of the enzyme(s), for example to reduce cannabinoid production in certain scenarios (e.g., during transport of the genetically modified organism to satisfy regulatory restrictions in certain jurisdictions, or between jurisdictions where cannabinoids may not be shipped). Non-limiting examples of inducible promoters include chemically regulated promoters and physically regulated promoters. For chemically regulated promoters, the transcriptional activity can be regulated by one or more compounds, such as alcohol, tetracycline, galactose, a steroid, a metal, an amino acid, or other compounds. For physically regulated promoters, transcriptional activity can be regulated by a phenomenon such as light or temperature. Non-limiting examples of tetracycline-regulated promoters include anhydrotetracycline (aTc)-responsive promoters and other tetracycline-responsive promoter systems (e.g., a tetracycline repressor protein (tetR), a tetracycline operator sequence (tetO) and a tetracycline transactivator fusion protein (tTA)). Non-limiting examples of steroid-regulated promoters include promoters based on the rat glucocorticoid receptor, human estrogen receptor, moth ecdysone receptors, and promoters from the steroid/retinoid/thyroid receptor superfamily. Non-limiting examples of metal-regulated promoters include promoters derived from metallothionein (proteins that bind and sequester metal ions) genes. Non-limiting examples of pathogenesis-regulated promoters include promoters induced by salicylic acid, ethylene or benzothiadiazole (BTH). Non-limiting examples of temperature/heat-inducible promoters include heat shock promoters. Non-limiting examples of light-regulated promoters include light responsive promoters from plant cells. In certain embodiments, the inducible promoter is a galactose-inducible promoter. In some embodiments, the inducible promoter is induced by one or more physiological conditions (e.g., pH, temperature, radiation, osmotic pressure, saline gradients, cell surface binding, or concentration of one or more extrinsic or intrinsic inducing agents). Non-limiting examples of an extrinsic inducer or inducing agent include amino acids and amino acid analogs, saccharides and polysaccharides, nucleic acids, protein transcriptional activators and repressors, cytokines, toxins, petroleum-based compounds, metal containing compounds, salts, ions, enzyme substrate analogs, hormones or any combination.

In some embodiments, the promoter is a constitutive promoter. As used in this application, a “constitutive promoter” refers to an unregulated promoter that allows continuous transcription of a gene. Non-limiting examples of a constitutive promoter include TDH3, PGK1, PKC1, PDC1, TEF, TEF2, RPL18B, SSA1, TDH2, PYK1, TPI1, HXT3, HXT7, ACT1, ADH1, ADH2, ENO2, and SOD1.

Other inducible promoters or constitutive promoters, including synthetic promoters, that may be known to one of ordinary skill in the art are also contemplated.

The precise nature of the regulatory sequences needed for gene expression may vary between species or cell types, but generally include, as necessary, 5′ non-transcribed and 5′ non-translated sequences involved with the initiation of transcription and translation respectively, such as a TATA box, capping sequence, CAAT sequence, and the like. In particular, such 5′ non-transcribed regulatory sequences will include a promoter region which includes a promoter sequence for transcriptional control of the operably joined gene. Regulatory sequences may also include enhancer sequences or upstream activator sequences. The vectors disclosed may include 5′ leader or signal sequences. The regulatory sequence may also include a terminator sequence. In some embodiments, a terminator sequence marks the end of a gene in DNA during transcription. The choice and design of one or more appropriate vectors suitable for inducing expression of one or more genes described in this application in a heterologous organism is within the ability and discretion of one of ordinary skill in the art.

Expression vectors containing the necessary elements for expression are commercially available and known to one of ordinary skill in the art (see, e.g., Sambrook et al., Molecular Cloning: A Laboratory Manual, Fourth Edition, Cold Spring Harbor Laboratory Press, 2012).

Culturing of Host Cells

Any of the cells disclosed in this application can be cultured in media of any type (rich or minimal) and any composition prior to, during, and/or after contact and/or integration of a nucleic acid. The conditions of the culture or culturing process can be optimized through routine experimentation as would be understood by one of ordinary skill in the art. In some embodiments, the selected media is supplemented with various components. In some embodiments, the concentration and amount of a supplemental component is optimized. In some embodiments, other aspects of the media and growth conditions (e.g., pH, temperature, etc.) are optimized through routine experimentation. In some embodiments, the frequency that the media is supplemented with one or more supplemental components, and the amount of time that the cell is cultured, is optimized.

Culturing of the cells described in this application can be performed in culture vessels known and used in the art. In some embodiments, an aerated reaction vessel (e.g., a stirred tank reactor) is used to culture the cells. In some embodiments, a bioreactor or fermentor is used to culture the cell. Thus, in some embodiments, the cells are used in fermentation. As used in this application, the terms “bioreactor” and “fermentor” are interchangeably used and refer to an enclosure, or partial enclosure, in which a biological, biochemical and/or chemical reaction takes place that involves a living organism or part of a living organism. A “large-scale bioreactor” or “industrial-scale bioreactor” is a bioreactor that is used to generate a product on a commercial or quasi-commercial scale. Large scale bioreactors typically have volumes in the range of liters, hundreds of liters, thousands of liters, or more.

Non-limiting examples of bioreactors include: stirred tank fermentors, bioreactors agitated by rotating mixing devices, chemostats, bioreactors agitated by shaking devices, airlift fermentors, packed-bed reactors, fixed-bed reactors, fluidized bed bioreactors, bioreactors employing wave induced agitation, centrifugal bioreactors, roller bottles, and hollow fiber bioreactors, roller apparatuses (for example benchtop, cart-mounted, and/or automated varieties), vertically-stacked plates, spinner flasks, stirring or rocking flasks, shaken multi-well plates, MD bottles, T-flasks, Roux bottles, multiple-surface tissue culture propagators, modified fermentors, and coated beads (e.g., beads coated with serum proteins, nitrocellulose, or carboxymethyl cellulose to prevent cell attachment).

In some embodiments, the bioreactor includes a cell culture system where the cell (e.g., yeast cell) is in contact with moving liquids and/or gas bubbles. In some embodiments, the cell or cell culture is grown in suspension. In other embodiments, the cell or cell culture is attached to a solid phase carrier. Non-limiting examples of a carrier system includes microcarriers (e.g., polymer spheres, microbeads, and microdisks that can be porous or non-porous), cross-linked beads (e.g., dextran) charged with specific chemical groups (e.g., tertiary amine groups), 2D microcarriers including cells trapped in nonporous polymer fibers, 3D carriers (e.g., carrier fibers, hollow fibers, multicartridge reactors, and semi-permeable membranes that can comprising porous fibers), microcarriers having reduced ion exchange capacity, encapsulation cells, capillaries, and aggregates. In some embodiments, carriers are fabricated from materials such as dextran, gelatin, glass, or cellulose.

In some embodiments, industrial-scale processes are operated in continuous, semi-continuous or non-continuous modes. Non-limiting examples of operation modes are batch, fed batch, extended batch, repetitive batch, draw/fill, rotating-wall, spinning flask, and/or perfusion mode of operation. In some embodiments, a bioreactor allows continuous or semi-continuous replenishment of the substrate stock, for example a carbohydrate source and/or continuous or semi-continuous separation of the product, from the bioreactor.

In some embodiments, the bioreactor or fermentor includes a sensor and/or a control system to measure and/or adjust reaction parameters. Non-limiting examples of reaction parameters include biological parameters (e.g., growth rate, cell size, cell number, cell density, cell type, or cell state, etc.), chemical parameters (e.g., pH, redox-potential, concentration of reaction substrate and/or product, concentration of dissolved gases, such as oxygen concentration and CO₂ concentration, nutrient concentrations, metabolite concentrations, concentration of an oligopeptide, concentration of an amino acid, concentration of a vitamin, concentration of a hormone, concentration of an additive, serum concentration, ionic strength, concentration of an ion, relative humidity, molarity, osmolarity, concentration of other chemicals, for example buffering agents, adjuvants, or reaction by-products), physical/mechanical parameters (e.g., density, conductivity, degree of agitation, pressure, and flow rate, shear stress, shear rate, viscosity, color, turbidity, light absorption, mixing rate, conversion rate, as well as thermodynamic parameters, such as temperature, light intensity/quality, etc.). Sensors to measure the parameters described in this application are well known to one of ordinary skill in the relevant mechanical and electronic arts. Control systems to adjust the parameters in a bioreactor based on the inputs from a sensor described in this application are well known to one of ordinary skill in the art in bioreactor engineering.

In some embodiments, the method involves batch fermentation (e.g., shake flask fermentation). General considerations for batch fermentation (e.g., shake flask fermentation) include the level of oxygen and glucose. For example, batch fermentation (e.g., shake flask fermentation) may be oxygen and glucose limited, so in some embodiments, the capability of a strain to perform in a well-designed fed-batch fermentation is underestimated. Also, the final product (e.g., cannabinoid or cannabinoid precursor) may display some differences from the substrate in terms of solubility, toxicity, cellular accumulation and secretion and in some embodiments can have different fermentation kinetics.

In some embodiments, the cells of the present disclosure are adapted to produce cannabinoids or cannabinoid precursors in vivo. In some embodiments, the cells are adapted to secrete one or more enzymes for cannabinoid synthesis (e.g., AAE, PKS, PKC, PT, or TS). In some embodiments, the cells of the present disclosure are lysed, and the remaining lysates are recovered for subsequent use. In such embodiments, the secreted or lysed enzyme can catalyze reactions for the production of a cannabinoid or precursor by bioconversion in an in vitro or ex vivo process. In some embodiments, any and all conversions described in this application can be conducted chemically or enzymatically, in vitro or in vivo.

Purification and Further Processing

In some embodiments, any of the methods described in this application may include isolation and/or purification of the cannabinoids and/or cannabinoid precursors produced (e.g., produced in a bioreactor). For example, the isolation and/or purification can involve one or more of cell lysis, centrifugation, extraction, column chromatography, distillation, crystallization, and lyophilization.

The methods described in this application encompass production of any cannabinoid or cannabinoid precursor known in the art. Cannabinoids or cannabinoid precursors produced by any of the recombinant cells disclosed in this application or any of the in vitro methods described in this application may be identified and extracted using any method known in the art. Mass spectrometry (e.g., LC-MS, GC-MS) is a non-limiting example of a method for identification and may be used to extract a compound of interest.

In some embodiments, any of the methods described in this application further comprise decarboxylation of a cannabinoid or cannabinoid precursor. As a non-limiting example, the acid form of a cannabinoid or cannabinoid precursor may be heated (e.g., at least 90° C.) to decarboxylate the cannabinoid or cannabinoid precursor. See, e.g., U.S. Pat. Nos. 10,159,908, 10,143,706, 9,908,832 and 7,344,736. See also, e.g., Wang et al., Cannabis Cannabinoid Res. 2016; 1(1): 262-271.

Liquid dosage forms for oral and parenteral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredients, the liquid dosage forms may comprise inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (e.g., cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. In certain embodiments for parenteral administration, the conjugates described in this application are mixed with solubilizing agents such as Cremophor®, alcohols, oils, modified oils, glycols, polysorbates, cyclodextrins, polymers, and mixtures thereof.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension, or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P., and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil can be employed including synthetic mono- or di-glycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form may be accomplished by dissolving or suspending the drug in an oil vehicle.

Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the conjugates described in this application with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol, or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.

Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or (a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, (c) humectants such as glycerol, (d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (e) solution retarding agents such as paraffin, (f) absorption accelerators such as quaternary ammonium compounds, (g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, (h) absorbents such as kaolin and bentonite clay, and (i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets, and pills, the dosage form may include a buffering agent.

EXAMPLES Example 1: Functional Expression of AAE Genes in E. coli and S. cerevisiae

It was reported previously that S. cerevisiae has endogenous AAE activity that allows conversion of hexanoate to hexanoyl-CoA (Gagne et al. 2012). However, in some embodiments, the endogenous AAE activity of S. cerevisiae may be insufficient for industrial-scale synthesis of downstream products. This example validates novel genes with AAE activity that can be used in the cells, reactions, and methods of the present disclosure.

Several DNA sequences with predicted AAE functionality were identified from the genomes of the yeast Yarrowia lipolytica (Y. lipolytica) and the bacterium Rhodopseudomonas palustris (R. palustris). The predicted AAE genes were first codon-optimized in silico for expression in E. coli. The codon-optimized gene sequences were synthesized via standard DNA synthesis techniques and were expressed in recombinant E. coli host cells (FIG. 4). Lysates from the recombinant E. coli host cells were then tested for AAE activity using an assay described below.

FIG. 4 shows the results from the AAE activity assay in E. coli host cells. 3 out of 4 predicted Y. lipolytica AAEs (strains t49578, t49594, and t51477) and both of the predicted R. palustris AAEs (strains t55127 and t55128) exhibited activity on a hexanoate substrate. Strains t49594 and t51477 expressed the candidate AAE enzyme as a fusion protein with an N-terminal MYC tag. In addition, the assays also showed that 2 out of 4 predicted Y. lipolytica AAEs (strains t49594 and t51477) and both of the predicted R. palustris AAEs (strains t55127 and t55128) also demonstrated activity on a butyrate substrate.

The newly described AAEs were also found to be capable of exhibiting AAE activity in eukaryotes. Briefly, the Y. lipolytica AAE that produced the best results in E. coli host cells was selected. This corresponded to the AAE expressed by strain t49594 (which encodes a protein corresponding to the protein provided by Uniprot Accession No. Q6C577 with a N-terminal MYC tag). The gene encoding this AAE was codon-optimized for expression in S. cerevisiae, and the last three residues (peroxisomal targeting signal 1) were removed. Two different codon-optimized versions of this AAE were synthesized in the replicative yeast expression vector shown in FIGS. 5A-5B. The recoded sequences only shared 81.66% sequence identity at the DNA level, while encoding for the same polypeptide. Both AAE expression constructs were then transformed into a CEN.PK S. cerevisiae strain, and transformants were selected based on ability to grow on media lacking uracil. The transformants were tested for AAE activity with a colorimetric AAE assay (described below). An S. cerevisiae strain expressing GFP was used as a negative control (strain t390338).

The results from the colorimetric AAE assay are shown in FIG. 6. Both of the codon-optimized versions of the Y. lipolytica AAE (strains t392878 and t392879) exhibited AAE activity on a hexanoate substrate, demonstrating that the newly disclosed AAEs could also be used in eukaryotic hosts. These enzymes were thus demonstrated to be capable of catalyzing the first enzymatic step in microbial production of cannabinoids from carboxylic acids.

This Example demonstrates identification of AAEs that are capable of using hexanoate and butyrate as substrates to produce cannabinoid precursors. Detailed results for the AAE activity experiments in E. coli host cells are provided below in Table 3. Sequence information for strains described in this Example are provided in Table 4 at the end of the Examples section.

Materials and Methods

AAE Assay for E. coli

E. coli BL21 strains harboring a plasmid that contained AAE genes driven by a T7 promoter were inoculated from glycerol stocks into shake flasks with 25 mL LB and grown overnight at 37° C. with shaking at 250 RPM. The next day, strains were inoculated 1% (v/v) into LB and grown for 3-6 hours until an OD600 of ˜0.6 was attained. They were then induced with 1 mM IPTG and incubated overnight at 23° C. with shaking at 250 RPM. The next day, the cultures were harvested and pelleted. Cell pellets were lysed with BugBuster™ reagent (5 mL per g wet pellet) at 18° C. and shaken at 250 RPM for 20 min. Lysates were centrifuged at 4° C. and 4000 RPM for 20 min. The soluble fractions of the lysates were taken for the enzyme assay. The enzyme assay mixture contained 5 mM substrate (sodium hexanoate or sodium butyrate), 3 mM ATP, 1 mM CoA, 5 mM MgCl₂, and 100 mM HEPES (pH 7.5). 25 μL of E. coli lysates were added to 500 μL of assay mixture and allowed to react at 30° C., 250 RPM for 20 min. Assays were then quenched by adding 50 μL of the reaction to 50 μL of 2 mM DTNB. Absorbance was measured at 412 nm to quantify the decrease in free CoA.

AAE Assay for S. cerevisiae

5 μL/well of thawed glycerol stocks were stamped into 300 μL/well of SC-URA+4% dextrose in half-height deepwell plates, which were sealed with AeraSeal™ film. Samples were incubated at 30° C. and shaken at 1000 RPM in 80% humidity for 2 days. 10 μL/well of resulting precultures were stamped into 300 μL/well of SC-URA+4% dextrose in half-height deepwell plates, which were sealed with AeraSeal™ film. Samples wee incubated at 30° C. and shaken at 1000 RPM in 80% humidity for 3 days. 10 μL of resulting production cultures were stamped into 140 μL/well PBS in flat bottom plates. Optical measurements were taken on a plate reader, with absorbance measured at 600 nm and fluorescence at 528 nm with 485 mn excitation.

Production culture plates were centrifuged at 4000 RPM for 10 min. Supernatant was removed, and the plates of pellets were heat-sealed and frozen at −80° C.

Pellets were thawed and 200 μL Y-PER per well was added. Samples were agitated at room temperature for 20 minutes and then pelleted at 3500 RPM for 10 minutes. 500 μL of the clarified lysate was combined with 50 μL of feed buffer or CoA standard in clear bottom plates. Plates were then incubated at 30° C. and shaken at 1000 RPM in 80% humidity for 60 min. 1 μL of DTNB buffer was added to each well to a final concentration of 100 μM DTNB, and samples were agitated at room temperature for 15 minutes. Absorbance was measured at 412 nm to quantify the decrease in free CoA.

Example 2: Functional Expression of OLS Genes in S. cerevisiae

Functional expression of C. sativa olivetol synthase (OLS) and olivetolic acid cyclase (OAC) enzymes in S. cerevisiae was previously reported (Gagne et al. 2012). To identify other OLS genes that can be functionally expressed, a library of approximately 2000 OLS candidate genes was designed. The genes within the library were codon-optimized for expression in S. cerevisiae and synthesized in the replicative yeast expression vector shown in FIGS. 5A-5B. Each candidate OLS was transformed into an auxotrophic S. cerevisiae CEN.PK GAL80 knockout strain, and transformants were selected based on ability to grow on media lacking uracil. The transformants were tested for olivetol and olivetolic acid production from sodium hexanoate in vivo in a high-throughput primary screen, as described in the materials and methods section below. Top olivetol and/or olivetolic acid-producing strains that were identified in the primary screen were subsequently tested in a secondary screen to verify and further quantify olivetol and olivetolic acid production.

Numerous yeast transformants were observed to be capable of producing olivetol in the primary screen (FIG. 8). In particular, two of the top olivetol-producing strains were strain t395094 and strain t393991 (FIG. 8). These two strains were also found to be among the top olivetol-producing strains in the secondary screen.

When the OLS library described in this Example was designed and screened in the primary and secondary screens, it was expected that the strains expressed full-length candidate OLS enzymes. Specifically, strain t395094 was believed to express a full-length OLS protein from Araucaria cunninghamii (Hoop pine) (corresponding to Uniprot Accession No. A0A0D6QTX3) and strain t393991 was believed to express a full-length OLS protein from Cymbidium hybrid cultivar (corresponding to Uniprot Accession No. A0A088G5Z5). However, as explained further in Table 5 at the end of the Examples section, sequencing analysis of strains from the OLS library used for these screens later revealed that there was a 6-nucleotide deletion in the sequences of many of the genes encoding the OLS enzymes in the library. Specifically, this deletion affected all of the candidate OLSs expressed by the strains identified in FIGS. 8-10, including the candidate OLSs expressed by strains t395094 and t393991 (Table 5).

The 6-nucleotide deletion included the first two nucleotides within the start codon of the genes encoding the OLS enzymes. As one of ordinary skill in the art would appreciate, such a deletion may result in the truncation of one or more amino acids from the N-terminus of the proteins encoded by the affected genes, and such a deletion could potentially extend to the next in-frame methionine residue in the intended protein sequence. For example, strain t393991 expressed a truncated version of a codon-optimized nucleic acid encoding an OLS protein from Cymbidium hybrid cultivar (Table 5). The full-length Cymbidium hybrid cultivar protein corresponds to SEQ ID NO: 7. If the deletion in the nucleic acid encoding this OLS protein were to result in translation commencing from the next start codon within the same reading frame, this would result in an N-terminally truncated version of the full-length OLS protein from Cymbidium hybrid cultivar. A protein sequence for a truncated protein that commences from the next start codon within the same reading frame is provided by SEQ ID NO: 714. SEQ ID NO: 714 has a truncation of the first 86 amino acids of SEQ ID NO: 7 and is approximately 77.9% identical to SEQ ID NO: 7.

Due to the truncation of OLS candidate genes within the library, candidate OLS genes screened in this Example were independently screened again using a new library that expressed only full-length OLS genes (Example 3). As discussed in Example 3, screening with a full-length OLS library independently identified both the OLS protein from Araucaria cunninghamii (Hoop pine) (corresponding to Uniprot Accession No. A0A0D6QTX3) and the OLS protein from Cymbidium hybrid cultivar (corresponding to Uniprot Accession No. A0A088G5Z5), discussed above, verifying the identification of these candidate OLSs as being highly effective for olivetol production in recombinant host cells.

It was determined that the OLS enzymes expressed by positive control strains t339579 and t339582, depicted in FIGS. 8-10, were also affected by the 6-nucleotide deletion discussed above. Accordingly, the low amounts of olivetol and olivetolic acid produced by the strains labelled as positive controls in FIGS. 8-10 may have been caused by disrupted expression of these proteins due to truncation.

Identification of Bifunctional PKS-PKC Enzymes

It was previously observed that S. cerevisiae possesses native OAC activity which enables some amount of the OLS product, 3,5,7-trioxododecanoyl-CoA, to be converted to olivetolic acid instead of undergoing a spontaneous decarboxylative cyclization to olivetol in the absence of OAC activity (FIG. 1). Most strains tested in the primary screen were observed to produce a constant (i.e., fixed) ratio of olivetolic acid to olivetol (FIG. 10). Without wishing to be bound by any theory, the accumulation of olivetolic acid and olivetol in these strains may be due to the reported endogenous S. cerevisiae OAC activity competing with spontaneous conversion of 3,5,7-trioxododecanoyl-CoA to olivetol. Both products, olivetol and olivetolic acid, increase proportionally with their shared precursor.

However, multiple strains were identified in the primary screen that demonstrated olivetolic acid production outside of the constant olivetolic acid to olivetol ratio discussed above. Strain t393974 demonstrated the highest olivetolic acid production (FIG. 9). In particular, strain t393974 was observed to produce substantially more olivetolic acid than olivetol in the primary screen a quantity of olivetolic acid that was outside of the fixed ratio exhibited by other tested strains (FIG. 10). These data suggested that the OLS enzyme expressed by strain t393974 may be a bifunctional enzyme possessing both polyketide synthase and polyketide cyclase catalytic functions and may be capable of catalyzing both reactions R2 and R3 in FIG. 2, and, at least, both reactions R2a and R3a in FIG. 1 (“Bifunctional PKS-PKC”).

As discussed above, when the OLS library described in this Example was designed and screened in the primary and secondary screens, it was expected that the strains expressed full-length candidate OLS enzymes. Specifically, strain t393974 was believed to express a full-length OLS protein from Corchorus olitorius (Jute) (corresponding to UniProt Accession No. A0A1R3HSU5). However, as discussed above and explained further in Table 5 at the end of the Examples section, sequencing analysis of strains from the OLS library used for these screens later revealed that there was a 6-nucleotide deletion in the sequences of many of the genes encoding the OLS enzymes in the library, which affected all of the candidate OLSs expressed by the strains identified in FIGS. 8-10, including the candidate OLS expressed by strain t393974 (Table 5). Accordingly, strain t393974 expressed a truncated version of a codon-optimized nucleic acid encoding an OLS protein from Corchorus olitorius (Jute) (Table 5). The full-length Corchorus olitorius (Jute) protein corresponds to SEQ ID NO: 6.

Due to the sequence truncation of OLS candidate genes within the library, candidate OLS genes screened in this Example were independently screened again using a new library that expressed only full-length OLS genes (Example 3). As discussed in Example 3, screening with a full-length OLS library also independently identified the candidate OLS protein from Corchorus olitorius (Jute) (corresponding to UniProt Accession No. A0A1R3HSU5; SEQ ID NO: 6) as an OLS that produced both olivetol and olivetolic acid.

Materials and Methods OLS Assay

A library of approximately 2000 OLS enzymes was transformed into S. cerevisiae. 5 μL/well of thawed glycerol stocks were stamped into 300 μL/well of SC-URA+4% dextrose in half-height deepwell plates, which were sealed with AeraSeal™ films. Samples wee incubated at 30° C. and shaken at 1000 RPM in 80% humidity for 2 days. 10 μL/well of the resulting precultures were stamped into 300 μL/well of SC-URA+4% Dextrose+1 mM sodium hexanoate in half-height deepwell plates, which were sealed with AeraSeal™ films. Samples wee incubated at 30° C. and shaken at 1000 RPM in 80% humidity for 4 days. 10 μL/well of the resulting production cultures were stamped into 140 μL/well PBS in flat bottom plates. Optical measurements were taken on a plate reader, with absorbance measured at 600 nm and fluorescence at 528 nm with 485 mn excitation.

30 μL/well of production cultures were stamped into 270 μL/well of 100% methanol containing 300 μg/L 3-(3-Hydroxypropyl)phenol (3HPP) in half-height deepwell plates. Plates were heat sealed and frozen at −80° C. for two hours. Plates were then thawed for 30 minutes and spun down at 4° C. at 4000 rpm for 10 min. 75 μL of supernatant from each well of each plate was stamped into Corning 3694 (half area) plates, which were then submitted for LC-MS quantification of olivetol and olivetolic acid.

The experimental protocol for the secondary screen was the same as described above, except that four replicates per strain were tested and standard curves of both olivetol and olivetolic acid were prepared so that both products could be quantified.

Example 3: Generation and Screening of Full-Length OLS Library

As discussed in Example 2, sequencing analysis of strains from the OLS library used for the screening described in Example 2 revealed that many of the genes encoding the OLS enzymes in the library were inadvertently truncated N-terminally. This truncation affected all of the strains identified in FIGS. 8-10, including the positive control strains.

Accordingly, a new OLS library was generated to contain only OLS genes that produce full-length OLS enzymes. The full-length OLS library contained full-length versions of the approximately 2000 OLS enzymes from the original library described in Example 2 and also included approximately 900 additional candidate OLS enzymes. All candidate OLS enzymes were codon optimized for expression in S. cerevisiae. Strain t527340, comprising an OLS from C. sativa, was included in the library as a positive control, and strain t527338, comprising GFP, was included in the library as a negative control. A high-throughput primary screen was conducted with the full-length OLS library using the same OLS assay described in Example 2 with the following exceptions: all library members and controls were transformed into an auxotrophic CEN.PK strain that comprised a chromosomally integrated heterologous gene encoding AAE VcsA (Uniprot Accession Q6N4N8) from R. palustris; and neither sodium hexanoate nor sodium butyrate were included in the production cultures.

Top olivetol and/or olivetolic acid-producing strains from the high-throughput primary screen were carried over to a secondary screen to verify and further quantify olivetol production. The experimental protocol for the secondary screen was the same as the primary screen except that: four replicates per strain were tested; and one set of cultures was supplemented with 1 mM sodium hexanoate, while the second set of cultures was not supplemented with sodium hexanoate. Olivetol production was normalized to a positive control strain expressing a C. Sativa OLS. Table 7 provides results for strains that exhibited average normalized olivetol >1 and/or that produced higher amounts of olivetolic acid than the positive control in samples that were supplemented with sodium hexanoate. FIG. 12A depicts olivetol production in library strains supplemented with sodium hexanoate. FIG. 12B depicts olivetolic acid production in library strains supplemented with sodium hexanoate. Table 8 provides results for strains that exhibited average normalized olivetol >1 and/or that produced higher amounts of olivetolic acid than the positive control in samples that were not supplemented with sodium hexanoate. Table 6 provides sequence information for strains described in Tables 7 and 8. The Average Normalized Olivetol for each strain was calculated by taking the mean of the following ratio for each replicate of that strain: the ratio of olivetol to absorbance measured at 600 nm to average olivetol produced by the C. sativa OLS positive control in the same plate.

One of the top olivetol-producing strains identified in this Example was strain t527346, comprising an OLS enzyme from Cymbidium hybrid cultivar (Accession ID: A0A088G5Z5; SEQ ID NO: 7; Tables 6-8). As discussed above, this candidate OLS was also identified in the screening conducted in Example 2. Protein alignments conducted with BLASTP using default parameters identified two other OLS candidates that shared at least 90% identity with the OLS enzyme from Cymbidium hybrid cultivar (Accession ID: A0A088G5Z5; SEQ ID NO: 7). These strains were: strain t598916 (expressing an OLS corresponding to SEQ ID NO: 145) and strain t599231 (expressing an OLS corresponding to SEQ ID NO: 15) (Tables 6-8), which were 93.07% and 91.79%, identical to SEQ ID NO: 7, respectively.

Another notable olivetol-producing strain identified in this Example was strain t599285, comprising an OLS enzyme from Araucaria cunninghamii (Accession A0A0D6QTX3; SEQ ID NO: 17). As discussed above, this candidate OLS was also identified in the screening conducted in Example 2.

Consistent with the identification in Example 2 of a candidate OLS from Corchorus olitorius (Jute) as a potentially bifunctional OLS, strain t598084, comprising a full-length version of the Corchorus olitorius (Jute) OLS (corresponding to UniProt Accession No. A0A1R3HSU5; SEQ ID NO: 6) was independently identified in this Example as a candidate OLS that produced more olivetolic acid than a Cannabis OLS positive control, and produced more olivetolic acid than olivetol, based on average olivetol and olivetolic acid produced (Tables 6-8).

Example 4: Generation and Screening of C. sativa OLS Protein Engineering Library in S. cerevisiae

To identify C. sativa OLS (CsOLS) enzyme variants with improved olivetol production, a library comprised of approximately 1300 members was designed. The library included CsOLS enzymes containing single or multiple amino acid substitutions or deletions. Nucleotide sequences were codon-optimized for expression in S. cerevisiae and synthesized in the replicative yeast expression vector shown in FIGS. 5A-5B. Each candidate enzyme expression construct was transformed into an auxotrophic S. cerevisiae CEN.PK GAL80 knockout strain. Transformants were selected based on ability to grow on media lacking uracil. Strain t346317, carrying GFP, was included in the library as a negative control.

The library of candidate CsOLS enzyme variants was assayed for activity in a high-throughput primary screen using the OLS assay described in Example 2 (FIG. 13). LC-MS analysis revealed that approximately 95% of library members produced measurable amounts of olivetol.

The top olivetol and/or olivetolic acid-producing strains from the primary screen were carried over to a secondary screen to verify the results. The experimental protocol for the secondary screen was the same as the primary screen, except that four replicates per strain were tested and a standard curve for olivetol and olivetolic acid was generated so that the amount of olivetol and olivetolic acid could be quantified via LC-MS (FIG. 13.)

Multiple OLS variants were identified that were capable of producing olivetol (Table 9). In order to investigate where the point mutations in the OLS variants were located relative to the OLS enzyme structure, a 3D model of the wildtype C. sativa OLS protein (corresponding to SEQ ID NO: 5) was generated using Rosetta protein modeling software. The active site of the C. sativa OLS enzyme was identified based on the catalytic triad of residues described in Taura et al. (2009) FEBS Letters for OLS enzymes, consisting of residues H297, C157, and N330 in the C. sativa OLS enzyme. The active site was also defined to include a docked molecule of hexanoyl-CoA (OLS substrate). Residues were considered to be within the active site if they were within about 12 angstroms of any of the residues within the catalytic triad of the OLS enzyme and/or within about 12 angstroms of a docked substrate within the OLS enzyme.

A subset of OLS point mutations was identified that included strains that produced at least 10 mg/L olivetol and mapped to within the active site. This group of point mutations included: T17K, I23C, L25R, K51R, D54R, F64Y, V95A, T123C, A125S, Y153G, E196K, L201C, I207L, L241I, T247A, M267K, M267G, I273V, L277M, T296A, V307I, D320A, V324I, S326R, H328Y, S334P, S334A, T335C, R375T (Table 9). FIG. 17 provides a schematic of the 3D structure of the C. sativa OLS protein (corresponding to SEQ ID NO: 5), showing the catalytic triad, the bound hexanoyl-CoA substrate, and the cluster of point mutations identified within the active site.

OLS point mutations from strains that produced at least 10 mg/L olivetol and mapped to within about 8 angstroms of any of the residues within the catalytic triad of the OLS enzyme and/or within about 8 angstroms of a docked substrate within the OLS included: K51R, D54R, T123C, A125S, L201C, I207L, L241I, T247A, M267K, M267G, I273V, T296A, V307I, V324I, S326R, H328Y, S334P, T335C, and R375T. FIG. 16 provides a schematic of the 3D structure of the C. sativa OLS protein (corresponding to SEQ ID NO: 5), showing the catalytic triad, the bound hexanoyl-CoA substrate, and the cluster of point mutations identified within about 8 angstroms of any of the residues within the catalytic triad of the OLS enzyme and/or within about 8 angstroms of a docked substrate within the PKS.

The point mutation that was found to be associated with the most olivetol production was a T335C mutation in the C. sativa OLS sequence (Table 9). This residue maps to the active site of the OLS enzyme (FIGS. 16-17). In further support of the importance of this residue for olivetol production, at least 5 of the high-producing olivetol candidate OLSs identified in Example 3 contain a C residue at this position (strain IDs t527346 (SEQ ID NO: 7), t598265 (SEQ ID NO: 13), t598301 (SEQ ID NO: 7), t598916 (SEQ ID NO: 145), t598976 (SEQ ID NO: 8), t599231 (SEQ ID NO: 15)). Strains t527346 and t598301 comprise an OLS that has the same amino acid sequence but the OLS is encoded by different nucleic acid sequences.

Additional C. sativa OLS variants were identified that did not map within the active site, but which were observed to produce more than approximately 13 mg/L olivetol (Table 9). This group of point mutations included: I284Y, K100L, K116R, I278E, K108D, L348S, K71R, V92G, T128V, K100M, Y135V, P229A, T128A, T128I (Table 9).

Table 13 provides sequence information for strains described in Table 9.

Thus, novel variants of the C. sativa OLS protein that may be useful for olivetol production in recombinant host cells were identified.

Example 5. Generation and Screening of C. sativa OLS (CsOLS), Cymbidium OLS (ChOLS), and Corchorus OLS (CoOLS) Protein Engineering Libraries in S. cerevisiae

An additional OLS protein engineering library was generated that included OLS variants based on three different OLS templates: C. sativa OLS (CsOLS); Cymbidium hybrid cultivar OLS (ChOLS) and Corchorus olitorius OLS (CoOLS), which were among the candidate OLSs identified in the screens described in Examples 2 and 3. As discussed above, ChOLS was identified as being one of the strongest olivetol-producing candidate OLS enzymes, while CoOLS was identified as being a potential bifunctional enzyme possessing both polyketide synthase and polyketide cyclase catalytic functions.

The library included approximately 300 variants of ChOLS and approximately 200 variants of CoOLS. Variants of ChOLS and CoOLS included both single and multiple amino acid substitutions. For ChOLS, some of the variants were designed by taking beneficial mutations discovered from screening of CsOLS variants described in Example 4 and mapping the corresponding mutations onto the ChOLS template. Corresponding positions in ChOLS were identified and mutated.

For CoOLS, some of the variants were designed to investigate whether there were any specific residues that may contribute to conferring or enhancing bifunctionality. The sequence of the bifunctional CoOLS enzyme (SEQ ID NO: 6) was aligned with the sequence of the CsOLS enzyme (SEQ ID NO: 5), which is not bifunctional, and residues that are different between the sequences were considered for mutagenesis in both the CsOLS and CoOLS sequences. The impact of these mutations on bifunctionality was investigated by measuring the ratio of production of olivetolic acid to olivetol. A specific residue that was investigated with respect to bifunctionality was residue W339 in CoOLS, which corresponds to residue S332 in CsOLS.

Nucleotide sequences of the genes within the library were codon-optimized for expression in S. cerevisiae and synthesized in the replicative yeast expression vector shown in FIGS. 5A-5B. Each candidate OLS expression construct was transformed into a S. cerevisiae CEN.PK strain expressing a heterologous AAE VcsA-Q6N4N8 from R. palustris. The library was screened in a high-throughput primary screen in which the OLS assay was conducted as described in Example 2, except that production cultures were not supplemented with either sodium hexanoate or sodium butyrate. Instead the strains' natural pools of hexanoyl-CoA and butyryl-CoA were used as substrates. Top olivetol and/or olivetolic acid producing strains were carried over to a secondary screen to verify production of olivetol and/or olivetolic acid. The experimental protocol for the secondary screen was identical to the primary screen, except that four replicates per strain were tested; and olivetol production was assessed both in the context of production cultures being supplemented with sodium hexanoate and in the context of production cultures that were not being supplemented with sodium hexanoate.

Strain t527338, expressing a fluorescent protein, was included in the library as a negative control for enzyme activity. Strain t527340, expressing wild-type CsOLS, was included in the library as a positive control. Strain t527346, expressing wild-type ChOLS, was included in the library as a positive control and was used to establish hit ranking for variants designed using ChOLS as a template. Similarly, strain t606797, expressing wild-type CoOLS, was included in the library as a positive control and was used to establish hit ranking for variants designed using CoOLS as a template. Olivetol was normalized to the mean production of its wild-type template (e.g., olivetol produced by a variant of ChOLS was normalized to the mean olivetol titer produced by strain t527346) except that for variants made to the CoOLS template, olivetol was normalized against each of a CsOLS template and a CoOLS template due to inconsistent activity of the CoOLS wild type control (Tables 10A-B and 11A-B). The Average Normalized Olivetol value for wild-type templates was not necessarily 1.0. For example, for the wild-type C. sativa strain t527340 in Table 10B, the Average Normalized Olivetol value was 1.02159. This was because the mean by which values were normalized was based on library controls that were included on each plate within a screen (e.g., strain t527340). The library further contained additional in-library controls of the same strain (e.g., strain t527340). Those additional in-library controls were not used to calculate the mean. In instances where the average normalized olivetol values for all samples of strain t527340 were calculated, if the in-library controls produced slightly more olivetol than the mean olivetol produced by the library controls that were included on each plate, then the Average Normalized Olivetol value was slightly above 1.0.

Results from the secondary screen are provided in Tables 10-11. Table 10 provides results for samples that were supplemented with sodium hexanoate, while Table 11 provides results for samples that were not supplemented with sodium hexanoate. In Table 10, strains comprising ChOLS mutants that produced an average normalized olivetol level of at least 0.5 are shown. The performance of multi-mutation ChOLS enzymes are also shown.

For ChOLS, the approach of mapping equivalent variants from the CsOLS sequence led to the identification of multiple variants that exhibited improved olivetol production. These variants included the following point mutations: V71Y, F70M, L385M, E285A, L76I, N151P, E203K, V50N, S34Q, R100P, A219C, K359M, and R100T (Table 11). Several additional variants exhibited improved olivetol production in samples that were supplemented with sodium hexanoate. These variants included the following point mutations: V71Y and F70M (Table 10).

For CoOLS, when the mutation W339S was made to the CoOLS template (strain t607112), the ratio of olivetolic acid to olivetol decreased, from approximately 1.5 to approximately 0.157 (based on 517.075 ug/L olivetol and 81.225 ug/L olivetolic acid, as shown in Table 10A). However, olivetol levels reported in Table 10A for strain t607112 were within the standard deviation. Accordingly, while the mutation may have had an impact on bifunctionality, it also appears to have more generally affected overall functionality of the enzyme. The reverse mutation was also tested in CsOLS. For CsOLS, S332W (strain t606899) had a significantly negative impact on the function of the enzyme (Table 10A). Similarly, mutation S339W in ChOLS (strain t607377) had a significantly negative impact on the overall function of the enzyme (Table 10A).

Example 6. Functional Expression of OLS Enzymes in a Prototrophic S. cerevisiae Strain

Examples 2-5 utilized an auxotrophic S. cerevisiae CEN.PK strain as a host chassis for the expression of OLS enzyme candidates from a replicative plasmid. OLS candidate enzymes determined to be active in Examples 2-5 were also assessed in a prototrophic S. cerevisiae CEN.PK strain.

A library of approximately 58 OLS genes under the control of the same genetic regulatory elements shown in FIGS. 5A-5B (GAL1 promoter and CYC1 terminator) were integrated into the genome of a prototrophic S. cerevisiae CEN.PK strain. The parental chassis strain t473139, not expressing a heterologous OLS enzyme, was included as a negative control for enzyme activity. Strain t496084, expressing the CsOLS T335C point-mutant, which was the highest ranking CsOLS point mutant identified in Example 5 based on production of olivetol, was also included. The OLS assay was conducted as described in Example 2 with the following exceptions: glycerol stocks were stamped into YEP+4% glucose; a portion of the resulting cultures were then stamped into production cultures containing YEP+4% glucose+1 mM sodium hexanoate; and three bio-replicates were used instead of two.

Despite differences between auxotrophic and prototrophic strains that may impact production of olivetol, candidate OLS enzymes identified in Examples 2-5 through screening in auxotrophic strains were also found to be effective in production of olivetol in a prototrophic strain (Table 12 and FIG. 15). As shown in Table 12, strain t496073, corresponding to a prototrophic S. cerevisiae strain comprising a chromosomally integrated, codon-optimized nucleotide sequence encoding the OLS candidate from Cymbidium hybrid cultivar (Accession ID: A0A088G5Z5), which was identified in Examples 2 and 3, produced the highest olivetol titer of any library member and significantly more olivetol than the C. sativa control (FIG. 15 and Table 12).

Thus, novel candidate OLS enzymes identified in Examples 2-5 were found to be effective for olivetol production when expressed in prototrophic strains as well as auxotrophic strains.

Example 7. Biosynthesis of Cannabinoids in Engineered S. cerevisiae Host Cells

The activation of an organic acid to its CoA-thioester and the subsequent condensation of this thioester with a number of malonyl-CoA molecules, or other similar polyketide extender units, represent the first two steps in the biosynthesis of all known cannabinoids. To demonstrate the biosynthesis of CBGA (FIG. 1, Formula (8a)), CBDA (FIG. 1, Formula (9a)), THCA (FIG. 1, Formula (10a)), and CBCA (FIG. 1, Formula (11a)) the cannabinoid biosynthetic pathway shown in FIG. 1 is assembled in the genome of a prototrophic S. cerevisiae CEN.PK host cell wherein each enzyme (Rla-R5a) may be present in one or more copies. For example, the S. cerevisiae host cell may express one or more copies of one or more of: an AAE, an OLS, an OAC, a CBGAS, and a TS.

An AAE enzyme expressed heterologously in a host cell may be one or more of the AAE candidates from Y. lipolytica or R. palustris that are shown in Example 1 to be functionally expressed in S. cerevisiae. An OLS enzyme expressed heterologously in a host cell may be an OLS identified and characterized in Examples 2-8, such as a Cymbidium hybrid cultivar OLS (SEQ ID NO: 7) or a Phalaenopsis x Doritaenopsis hybrid cultivar OLS (SEQ ID NO: 15), or an OLS corresponding to SEQ ID NO: 145. The OLS enzyme may also be an engineered OLS such as CsOLS T335C (SEQ ID NO: 207) or an engineered version of any other OLS enzyme described in this disclosure. An OAC enzyme expressed heterologously in a host cell may be a naturally occurring or synthetic OAC that is functionally expressed in S. cerevisiae, or a variant thereof, including an OAC from C. sativa or a variant of an OAC from C. sativa. In instances where a bifunctional OLS, such as Corchorus olitorius OLS (SEQ ID NO: 6), is used, a separate OAC enzyme may be omitted.

A CBGAS enzyme, such as a PT enzyme, expressed heterologously in a host cell may be a naturally occurring or synthetic PT that is functionally expressed in S. cerevisiae, or a variant thereof, including a PT from C. sativa or a variant of a PT from C. sativa. For example, a PT may comprise CsPT4 from C. sativa, or a variant thereof, or NphB from Streptomyces sp. Strain CL190, or a variant thereof.

A TS enzyme expressed heterologously in a host cell may be a naturally occurring or synthetic TS that is functionally expressed in S. cerevisiae, or a variant thereof, including a TS from C. sativa or a variant of a TS from C. sativa. The TS enzyme may be a TS that produces one or more of CBDA, THCA, and CBCA as a majority product.

The cannabinoid fermentation procedure may be similar to the OLS assay described in the Examples above with the following exceptions: the incubation of production cultures may last from, for example, 48-144 hours, and production cultures may be supplemented with, for example, 4% galactose and 1 mM sodium hexanoate approximately every 24 hours. Titers of CBGA, CBDA, THCA, and CBCA may be quantified via LC-MS.
